2013 NFL season

Player movement

The 2013 league year began at 4 pm EST on March 12, which marked the start of the league's free agency period. The per-team salary cap was set at US$123,000,000. For the first time the league instituted a negotiating period prior to the start of free agency during which time agents representing prospective unrestricted free agent players (though not the players themselves) were allowed to have contact with team representatives with the purpose of determining a player's market value and to begin contract negotiations. This period, which was referred to by some as the "legal tampering" period, began at midnight on March 9.

Free agency

A total of 524 players were eligible for some form of free agency. Among the high-profile players who changed teams via free agency were wide receivers Mike Wallace (left the Steelers, joined the Dolphins), Greg Jennings (from Packers to Vikings) and Wes Welker (from Patriots to Broncos); defensive end Cliff Avril (from Lions to Seahawks); safety Dashon Goldson (from 49ers to Buccaneers); offensive tackle Jake Long (from Dolphins to Rams); and running backs Steven Jackson (from Rams to Falcons) and Reggie Bush (from Dolphins to Lions).

Eight players were assigned the non-exclusive franchise tag by their teams, which ensured that the team would receive compensation were the player to sign a contract with another team. These players were Brandon Albert (Chiefs), Jairus Byrd (Bills), Ryan Clady (Broncos), Michael Johnson (Bengals), Pat McAfee (Colts), Henry Melton (Bears), Anthony Spencer (Cowboys) and Randy Starks (Dolphins). None of these players changed teams.

Major trades

The following trades are notable as they involved Pro Bowl-caliber players and/or draft picks in the first three rounds:

Draft

The 2013 NFL Draft was held April 25–27, 2013, in New York City. Prior to the draft the NFL Scouting Combine, where draft-eligible players were evaluated by team personnel, was held in Indianapolis on February 20–26. In the draft the Kansas City Chiefs made Central Michigan University offensive tackle Eric Fisher the first overall selection.

Preseason

Training camps for the 2013 season opened in late July. The Buccaneers camp was the first to open with rookies reporting on July 17. The Cowboys were the first to open camp to veteran players on July 20. All teams were in camp by July 27.

Prior to the start of the regular season, each team played at least four preseason exhibition games. The preseason schedule got underway with the NFL Hall of Fame Game on Sunday, August 4. The Hall of Fame game is a traditional part of the annual Pro Football Hall of Fame induction weekend celebrating new Hall of Fame members. It was played at Fawcett Stadium in Canton, Ohio, which is located adjacent to the Hall of Fame building. In the game, which was televised nationally on NBC, the Dallas Cowboys defeated the Miami Dolphins 24–20. The 2013 Hall of Fame class of Larry Allen, Cris Carter, Curley Culp, Jonathan Ogden, Bill Parcells, Dave Robinson and Warren Sapp was honored during the game. The 65-game preseason schedule concluded on Thursday, August 29.

Regular season

The 2013 season featured 256 games played out over a seventeen-week schedule which began on the Thursday night following Labor Day. Each of the league's 32 teams played a 16-game schedule which included one bye week for each team between weeks four and twelve. The slate featured seventeen games on Monday night including a doubleheader in the season's opening week. There were also seventeen games played on Thursday, including the National Football League Kickoff game in prime time on September 4 and three games on Thanksgiving Day. The regular season wrapped up with a full slate of 16 games on Sunday, December 29, all of which were intra-divisional matchups.

Under the NFL's scheduling formula, each team played each of the other three teams in their own division twice. In addition, a team played against all four teams in one other division from each conference. The final two games on a team's schedule were against the two teams in the team's own conference in the divisions the team was not set to play who finished the previous season in the same rank in their division (e.g. the team which finished first in its division the previous season would play each other team in their conference that also finished first in its respective division). The pre-set division pairings for 2013 were as follows:

The 2013 regular season schedule was released on April 18, 2013.

The 2013 regular season began on Thursday, September 5, with the NFL Kickoff Game in which the Denver Broncos hosted the Baltimore Ravens. The game was a rematch of a double-overtime playoff game of the previous season. The game was broadcast on NBC. The Ravens, as the reigning Super Bowl champions, would normally have hosted the kickoff game, however, a scheduling conflict with their Major League Baseball counterparts, the Baltimore Orioles, forced the Ravens to start the season on the road (the Ravens' and Orioles' respective stadiums — M&T Bank Stadium and Oriole Park at Camden Yards — share parking facilities). The Ravens became the first Super Bowl winner since 2003 to open their title defense on the road.

In the kickoff game the Broncos avenged their playoff loss by defeating the Ravens 49–27 on the strength of a record-setting performance by quarterback Peyton Manning. Manning put on an amazing show completing 27 of 42 pass attempts for 462 yards and seven touchdowns. Manning set or tied numerous league records in the game including most touchdown passes in a game (tied with five others) and records for most career games with at least six, five and four touchdown passes.

The first of two games in the NFL International Series was played in the fourth week of the season on September 29. The Minnesota Vikings hosted the Pittsburgh Steelers at Wembley Stadium in London, England. Both teams entered the game winless on the season at 0–3. The Steelers–Vikings game kicked off at 6:00 pm BST (1:00 pm EDT). The Jacksonville Jaguars hosted the San Francisco 49ers at Wembley four weeks later, in the first of four annual London games for the Jaguars running through 2016. The 49ers–Jaguars game started at 5:00 pm GMT (1:00 pm EDT). This was the first season which included two London games. It was announced in October that the International Series would be expanded to include three games in 2014.

The game that perhaps best exemplified the offensive explosion of the 2013 season was the Broncos' 51–48 victory over the Cowboys on October 6. This was the fourth highest-scoring game in history in a season in which new records were set for overall as well as per-game scoring. The teams combined for 1,039 yards in total offense. Cowboys quarterback Tony Romo passed for 506 yards, becoming only the fifth passer in league history to surpass 500 yards and throw five touchdown passes in a game. However, Romo threw an interception with the score tied in the game's final two minutes which led to a Matt Prater field goal which gave the Broncos the win as time ran out.

The Chargers and Raiders played an unusual late night game in the season's fifth week on October 6. The game, originally scheduled to start at 1:25 pm PDT, had to be moved to the evening to accommodate stadium schedules — Major League Baseball's Oakland Athletics, the Raiders' co-tenants of O.co Coliseum, had hosted the second game of the 2013 American League Division Series the previous night and stadium crews needed nearly 24 hours to convert the stadium from a baseball to a football configuration. O.co Coliseum was only multi-purpose stadium which hosted both an NFL and an MLB team in 2013. Although the stadium conversion was complete by 3:30 pm local time, an 8:36 pm kickoff was necessary to avoid conflict with NBC's Sunday Night Football, where the 49ers hosted the Texans at Candlestick Park across the San Francisco Bay. The Chargers-Raiders game was the latest game played on the west coast in league history and was broadcast nationwide on the NFL Network.

The highlight of the season's seventh week was the return of Broncos quarterback Peyton Manning to Indianapolis to play the Colts. Manning had played for the Colts the first fourteen years of his career before he was released by the team in March 2012, as he was coming off a serious neck injury which kept him out of the 2011 season. Manning was honored prior to the game in a 90-second video of the highlights of his years with the Colts. The Colts won the game 39–33 behind a four touchdown performance by Manning's replacement as the Colts starting quarterback, Andrew Luck. It was the Broncos' first loss on the season and broke a string of 19 consecutive regular season wins.

With the Broncos loss to the Colts, the Chiefs became the league's last unbeaten team of 2013. They would run their record to 9–0 before losing to the Broncos 27–17 in the season's eleventh week on November 17. The Chiefs had suffered a league-worst 2–14 season in 2012.

On November 24, the Patriots hosted the Broncos on NBC Sunday Night Football. The game featured the fourteenth meeting in the careers of two of the league's best quarterbacks, Patriots quarterback Tom Brady and Peyton Manning of the Broncos. The game was hyped as Manning-Brady XIV. The game lived up to the hype with Manning's Broncos building a 24–0 halftime lead as the Patriots were booed off their home field. In the second half Brady's Patriots scored 31 unanswered points. The Broncos scored a late touchdown to tie the game and send it into overtime where the Patriots ended the game on a field goal after recovering a muffed punt at the Broncos' 13-yard line. The comeback was the largest in Patriots history, until the Patriots overcame a 25-point deficit in Super Bowl 51.

The league's traditional slate of Thanksgiving Day games was played on Thursday, November 28. The Lions hosted the Packers in the early game at 12:30 pm EST, marking the Packers' 21st Thanksgiving game in Detroit. The Raiders visited the Cowboys in the late afternoon game at 3:30 pm CST. The evening game featured the defending Super Bowl champion Ravens hosting their AFC North rival Steelers at 8:30 pm EST.

Controversy erupted during the third quarter of the Thanksgiving night game between the Steelers and Ravens, as Steelers head coach Mike Tomlin found himself in the path of Ravens returner Jacoby Jones during a Ravens kickoff return. Tomlin was watching the play on the stadium's big screen and was thus facing away from the play itself while standing with at least one foot in the field of play. Jones broke the return to the side of the field and was running up the sideline on which Tomlin was standing. Tomlin stepped away from the field to avoid Jones as he approached, but did so only after he caused Jones to veer slightly toward the center of the field. Shortly thereafter, Jones was tackled from behind at the Steelers' 27 yard-line. Some observers speculated that without Tomlin's interference Jones may have reached the endzone on the play. Tomlin was fined $100,000 by the league for the incident and the league held out the possibility that the Steelers might also be stripped of draft picks in the 2014 NFL Draft since Tomlin's actions "affected a play on the field." After the season concluded it was announced that no further penalty beyond Tomlin's fine would be assessed.

The Bills hosted the Falcons in Toronto, Ontario, Canada on December 1. The game was played at Rogers Centre one week after the 101st Grey Cup ended the 2013 Canadian Football League season. On January 9, the Bills and Rogers Communications had announced a five-year extension of the Bills Toronto Series.

In contrast to the league-wide offensive explosion, the Seahawks fielded one of the best defenses in league history in 2013. Perhaps the best performance of the season for the Seahawks defense occurred in week 15 as they shut out the Giants 23–0. In the game the Seahawks intercepted five passes and forced the Giants to punt on all eight of their other possessions. The Giants' offense was held to just 181 yards for the game.

Going into the final day of the season on December 29, eighteen teams remained in contention for the twelve available playoff spots. All sixteen of the week seventeen games (all of which were intra-division matchups) were played on Sunday and thirteen had playoff implications. All four division winners in the AFC had been determined, but all four NFC divisions were still up for grabs. In the season's final regular season game on Sunday night, the Eagles defeated the Cowboys 24–22 to capture the NFC East. This was the third straight year that the Cowboys were eliminated from the playoffs with losses in their final game, all of which were against division rivals and all of which were played on Sunday night.

Postseason

The wild card round of the playoffs featured the two wild card playoff qualifiers from each conference being hosted by the two lowest seeded divisional winners. The top two seeds in each conference — the Seahawks, Panthers, Broncos and Patriots — all had first-round byes. The games were played January 4–5, 2014.

The weekend's first game on Saturday featured the Colts staging the second biggest comeback in playoff history to defeat the Chiefs by a score of 45–44. The 28-point second half deficit the Colts overcame is exceeded only by the Bills–Oilers playoff game from January 1993 which has become known simply as "The Comeback." It was the first time in any NFL game (regular or postseason) that a team won in regulation play (i.e. not overtime) after having trailed by as many as 28 points. The game was also the highest scoring postseason game to have been decided by a one-point margin as well as the first game in league history to finish with a 45–44 result. The Colts and Chiefs combined to gain 1,049 total yards which established a new single-game postseason record, breaking the record of 1,038 yards that was set by the Bills–Dolphins first-round game on December 30, 1995, and matched in a Saints–Lions first-round matchup on January 7, 2012. The loss was the Chiefs' eighth straight in the playoffs which broke an NFL record for consecutive playoff losses the franchise had previously shared with the Lions.

The Saints beat the Eagles 26–24 in the Saturday night game. It was the Saints' first ever road playoff victory. The Saints built an early 20–7 lead before the Eagles bounced back to take a 24–23 lead with less than five minutes remaining in the game. However, the Saints worked their way down the field while also working the clock on the game's final drive before Shayne Graham kicked the game-winning field goal from 32 yards out as time expired.

The early game on Sunday was the only game of the weekend not decided by three or fewer points with the Chargers defeating the Bengals, 27–10. Bengals quarterback Andy Dalton committed three second-half turnovers which led to the Chargers scoring 20 unanswered points to overcome a 7–10 halftime deficit. The Bengals loss marks a league record third straight year in which the team has lost its playoff opener, and extended the Bengals' streak of playoff futility to 23 seasons. Every other current NFL team has won a playoff game since the Bengals' last playoff victory in January 1991.

In the late afternoon game on Sunday the 49ers defeated the Packers on a brutally cold day at Lambeau Field. The temperature at game time was just 5 °F (−15 °C) with a wind chill of −10 °F (−23 °C). Quarterback Colin Kaepernick, who eschewed sleeves and gloves despite the chilly conditions, passed for 227 yards and rushed for 98 more to lead the 49ers to victory in a back-and-forth game. Phil Dawson kicked the winning field goal as time expired. This was the second straight year that the Packers' season had both started and ended with losses to the 49ers.

The divisional round games were played on January 11–12, 2014 and three of the four were rematches of regular season games — only the Patriots and Colts had not met in 2013.

In the early game on Saturday, the Seahawks defeated the Saints 23–15. The Seahawks held a 16–0 lead at halftime, but the Saints came back in the second half to make the game interesting. The Seahawks were able to hold on after a late Saints comeback effort, including an onside kick recovery, fell short. The Seahawks' offense centered around a 28 carry, 140 yard rushing effort from Marshawn Lynch, who also scored on a 31-yard run in the fourth quarter.

Patriots running back LeGarrette Blount and the Patriots defense were the stars of the Patriots 43–22 victory over the Colts in the Saturday night game. Blount rushed for 166 yards and a franchise-record four touchdowns while Colts quarterback Andrew Luck was intercepted four times. Patriots quarterback Tom Brady broke a league record for most playoff games for a starting quarterback with 25 (a record he had previously shared with Brett Favre) and extended his own record of 18 career playoff wins. The victory allowed the Patriots to reach the AFC Championship game for the third straight year as well as the eighth time with Brady and head coach Bill Belichick. Belichick moved into a second-place tie with Don Shula on the all-time postseason head coaching wins list, one victory behind Tom Landry.

The 49ers defeated the Panthers by a score of 23–10 in the early Sunday game. The 49ers defense twice stopped the Panthers one yard short of the end zone and also recorded two interceptions and five quarterback sacks. 49ers quarterback Colin Kaepernick threw for one touchdown and ran for another in the game. The win put the 49ers into their third straight and fifteenth overall conference championship game, matching the Pittsburgh Steelers for most conference championship appearances. Jim Harbaugh became the first head coach in NFL history to take his team to the conference championship game in each of his first three seasons.

In the final game of the divisional round the Broncos beat the Chargers 24–17. It was only the fourth time in the season to date that the Broncos had been held to fewer than 30 points (three of which were against the Chargers), but the Chargers offense could not capitalize. The Broncos held a 17–0 lead in the fourth quarter before the Chargers launched a comeback that was too little and too late. The win put the Broncos into the AFC championship game for the first time since the 2005 season.

The conference championships took place on Sunday, January 19, 2014.

The early game featured the Broncos hosting the Patriots in the AFC Championship Game. The game was referred to by many as Manning-Brady XV as it was the fifteenth meeting (the fourth in the playoffs) of the two starting quarterbacks, Tom Brady and Peyton Manning. The Broncos defeated the Brady and the Patriots 26–16 behind a 400-yard passing performance by Manning. Manning led the Broncos on two long touchdown drives which each used over seven minutes of game time and were the two longest drives in terms of game time of the Broncos season. This was Manning's third career postseason game with 400 or more yards passing, equaling Drew Brees for the most such playoff games in league history. Broncos head coach John Fox, who previously led the Carolina Panthers to Super Bowl XXXVIII in 2004, became the sixth head coach in NFL history to take two different franchises to the Super Bowl.

The NFC Championship Game had the Seahawks hosting the 49ers in the late game. The Seahawks defense forced three turnovers in the fourth quarter which proved to be the difference in the game. The last of these was a pass intended for Michael Crabtree in the endzone which was intercepted by Seahawks linebacker Malcolm Smith off a deflection by cornerback Richard Sherman with just 22 seconds remaining in the fourth quarter. The interception preserved a 23–17 Seahawks victory. In an on-field interview immediately after the game with Fox sideline reporter Erin Andrews, Sherman famously directed a rant at Crabtree whom Sherman called a "sorry receiver."

Super Bowl XLVIII

Super Bowl XLVIII featured the top seeded team from each conference for just the second time in twenty years. The Broncos possessed the league's best offense (in terms of both scoring and yards) while the Seahawks had the league's top defense (also in both scoring and yardage). The game was played on February 2, 2014 at MetLife Stadium in East Rutherford, New Jersey, just outside New York City and was televised in the U.S. by Fox with kickoff at 6:32 pm EST. This was the first ever Super Bowl to be staged outdoors in a cold weather environment although the temperature was a mild 49 degrees at kickoff.

The game started disastrously for the Broncos who, despite losing the coin toss, received the opening kickoff. On the game's first play from scrimmage from the Broncos' 14 yard line, Broncos center Manny Ramirez sent a shotgun snap over the head of quarterback Peyton Manning. The ball traveled into the endzone where it was covered by Broncos running back Knowshon Moreno who was touched down for a safety with just 12 seconds of game time elapsed. This was the quickest score ever in a Super Bowl. The Seahawks did not relinquish the lead in a 43–8 victory.

This was the Seahawks first ever league championship since entering the NFL in 1976. Seahawks linebacker Malcolm Smith, who scored on a 69-yard interception return, a fumble recovery and tallied 10 tackles, was named the game's Most Valuable Player (MVP).

This was the fifth Super Bowl loss for the Broncos, the most for any franchise. Even in defeat, though, Peyton Manning's record-breaking year continued. He set a record for most passes completed in a Super Bowl with 34. He also moved ahead of Tom Brady into first place on the career playoff passing yardage list with 6,589 yards. In addition, Broncos wide receiver Demaryius Thomas caught 13 passes to set a single-game Super Bowl record.

Pro Bowl

The Pro Bowl is the league's all-star game. The league had raised doubts about the future of the exhibition due to concerns over the game's competitiveness in recent years, but on March 20, it was announced that the 2014 Pro Bowl would indeed take place, receiving a one-year reprieve. As in recent years, the game was held the week before the Super Bowl at Aloha Stadium in Honolulu, Hawaii. It was played on Sunday, January 26, and broadcast in the U.S. on NBC.

The format for the game was considerably altered in an effort to improve competitiveness. The biggest changes included an "unconferenced" format in which players would be selected regardless of the conference in which their team competes, a draft format to select the teams and various tweaks to increase the excitement of the game itself. Deion Sanders and Jerry Rice served as the non-playing captains for the two competing squads.

Notable events

Some NFL-related events that made headlines throughout 2013 include:

A nationwide poll conducted by Harris Interactive in December 2013 concluded that pro football is the favorite sport of Americans. Of the respondents asked the question, "If you had to choose, which ONE of these sports would you say is your favorite?", 35% chose pro football. That is up by one percentage point over the results of the previous year. Football has taken the top spot in the annual poll each year since it was first conducted in 1985. Baseball finished second, with 14% naming it as their favorite, followed by college football at 11%.

In August, former Patriots tight end Aaron Hernandez was charged with the murder of Odin Lloyd. Hernandez was released by the Patriots following his arrest in the murder investigation in June. In an effort to further distance themselves from the troubled Hernandez, the Patriots offered fans an opportunity to trade-in Hernandez jerseys for another jersey of comparable value. Hernandez would be convicted of the murder charge and sentenced to life imprisonment in April 2015.

Eagles wide receiver Riley Cooper was caught on video using a racial slur during a music concert. After the video went viral during the team's training camp, Cooper was briefly sent away from the team to seek counseling. The Eagles also levied an undisclosed fine.

In August, just prior to the start of the season, a US$765,000,000 settlement proposal was announced in a class-action lawsuit brought against the league by former players who contended that the league concealed a link between head injuries sustained by players and traumatic brain injury which may only become apparent later in life. The judge in the case later rejected the settlement on the grounds that the amount may not be large enough to cover the needs of all the plaintiffs.

In October, the Buccaneers released quarterback Josh Freeman after trying unsuccessfully to trade him. Freeman had been considered one of the league's best young quarterbacks after leading the Bucs to a 10–6 record in 2010, but he clashed with head coach Greg Schiano (who took over in 2012) and was benched earlier in the year. Despite being just 25 years old, Freeman held franchise records for touchdowns and completions and was second in passing yardage. It had come out earlier in the week that Freeman had been in the league's substance abuse program; Freeman described his participation as voluntary and a result of prescription drugs he was taking to treat ADHD. Shortly after his release, Freeman was signed by the Vikings. Freeman started for the Vikings in week seven, but he posted a passer rating of just 40.6 in that game and did not play another down during the season. He was inactive for nine of the Vikings' final ten games.

Three Buccaneers players — kicker Lawrence Tynes, guard Carl Nicks and cornerback Johnthan Banks — were diagnosed with Methicillin-resistant Staphylococcus aureus (MRSA) infections during the season. The potentially deadly strain of staph had been encountered by other NFL teams including the Washington Redskins, St. Louis Rams and Cleveland Browns in previous seasons. After the third infection was confirmed there was brief discussion as to whether the Bucs' week six home game against the Eagles would be played, but the decision was made to continue with the scheduled game. The Falcons even took the step of bringing in a hazardous materials crew to disinfect the visitor's locker room after the Bucs' visited Atlanta in week seven.

Dolphins offensive lineman Richie Incognito was suspended by the team in November after allegations surfaced that he bullied fellow lineman Jonathan Martin who left the team earlier in the season due to the impact of Incognito's actions.

The league's official investigation into the matter concluded that Martin and other Dolphins employees had been subjected to a "pattern of harassment" at the hands of Incognito as well as fellow linemen John Jerry and Mike Pouncey. The 144-page report, written by league-appointed investigator Ted Wells, called the situation a "classic case of bullying". The report also implicated Dolphins offensive line coach Jim Turner in some of the abuse; Turner was fired by the team shortly after the report's release.

Redskins head coach Mike Shanahan made a decision to bench the team's franchise quarterback, Robert Griffin III for the team's final three games of the 2013 season. Griffin had undergone knee surgery after being injured the previous season in which he was named NFL Offensive Rookie of the Year after being selected second overall in the 2012 draft. Griffin was much less productive in his second season. Shanahan stated that the decision to start Kirk Cousins over Griffin was made to protect Griffin from sustaining another injury, although there was speculation that Shanahan was unhappy about Griffin's friendly relationship with team owner Daniel Snyder. Shanahan was fired after the season ended.

Russell Wilson the second-year quarterback of the Super Bowl champion Seahawks led all NFL players in terms of total licensed product sales (jerseys, T-shirts, figurines, photos, etc.) made from March 2013 through February 2014. The top six players on the list were quarterbacks, including, in order, Peyton Manning (who held the top spot the previous year), Colin Kaepernick, Robert Griffin III, Aaron Rodgers and Tom Brady. The only non-quarterback in the top 10 was Wilson's Seahawks teammate, running back Marshawn Lynch.

Legendary Hall of Fame defensive lineman Deacon Jones died in June. Shortly thereafter the league honored Jones' legacy by creating the "Deacon Jones Award" to be given annually to the player who records the most quarterback sacks. Colts linebacker Robert Mathis was the inaugural winner of the honor.

Tennessee Titans owner Kenneth S. "Bud" Adams died in October. He was the only owner the franchise, which began in 1960 as the Houston Oilers in the AFL, has ever had. Adams was a second-generation oil tycoon who made his home in Houston, Texas. The team was inherited in equal parts by the families of Adams' three children with Adams' son-in-law Tommy Smith succeeding Adams as the president and CEO of the franchise.

Aside from those mentioned above, the following people associated with the NFL died in 2013: Hall of Fame members Jack Butler, Art Donovan, Mike McCormack and Clarence "Ace" Parker; former coaches Bill Austin, Chuck Fairbanks, John Idzik, John Mazur, Jack Pardee, Jim Sweeney, Bum Phillips and Ray Willsey; former players Scott Adams, Tom Alberghini, Bill Albright, John Alderton, Jim Barton, Hezekiah Braxton, Don Brown, George Brown (1949 New York Yankees of the AAFC), Tom Brown, Ted Burgmeier (1987 Kansas City Chiefs), Jim Canady (1948 Chicago Bears), Rick Casares, Jim Cason, Frank Chamberlin, Todd Christensen, Ken Clark, Walt Clay (1946 Chicago Rockets of the AAFC), Ray Coates (1949 N.Y.

Stadium changes

2013 marked the final season in which the Minnesota Vikings played their home games at the Hubert H. Humphrey Metrodome, as the team will move temporarily to TCF Bank Stadium (home of the University of Minnesota Golden Gophers) while their U.S. Bank Stadium is built at the same site as the Metrodome. The Vikings will play the 2014 and 2015 seasons at TCF Bank Stadium and open their new stadium for the 2016 season. The Vikings had called the Metrodome home since it opened in 1982.

This was also the final season in which the San Francisco 49ers played their home games at Candlestick Park, as the team will move into the newly built Levi's Stadium located in Santa Clara, California, for 2014.
