The Giants once again dominated the game from the get go, racing out to a 38-14 lead late in the third quarter. But Jeff Garcia once again led the 49ers back, this time in one of the most incredible comebacks in football history. He rallied San Francisco to three touchdown drives (and a two point conversion on one of them) and a field goal for 25 unanswered points to give the 49ers a 39-38 lead with a minute to go. But the Giants had one more chance. QB Kerry Collins drove the Giants down to San Francisco's 23 yard line, where they set up for the game winning field goal with six seconds left. But the snap from Trey Junkin was too low, and holder Matt Allen was forced to scramble and heave a desperation last gasp pass, which fell incomplete, and the 49ers won, 39-38.

But the result of the game stood.
