Due to a rules change during the postseason of 1995, college football games can't end in a tie. At the beginning of the 1996 season, the NCAA Football Rules Committee added an overtime procedure to end the chance of a tied game.
Overtime in a college football game is not a timed period of play. Instead, each team receives one possession and begins with a first-and-ten from a fixed point on the opponent's side of the field. If the score remains tied, the procedure begins again. The only way the game can end with one possession is if the defense forces a fumble or intercepts the ball and returns it for a score.
