It is illegal for any player to put adhesive or slippery substances such as the product "stickum" on his body, equipment or uniform. This rule is known as both the "Lester Hayes Rule" and the "Fred Biletnikoff Rule" since both players were notorious for using sticky substances to make it easier for them to intercept/catch passes.An offensive player who comes into the game wearing an illegal number for the position he takes must report to the Referee before the start of the next play.The penalty for an ineligible receiver who touches a forward pass is a loss of down.The penalty for illegal use of hands, arms, or body (including holding) is reduced from 15 yards to 10 yards.The penalty for intentional grounding is modified: loss of down and 10 yards penalty from the previous spot, or if the foul occurs more than 10 yards from the line of scrimmage, loss of down at the spot of the foul.Final standings
