There are different rules for overtime in the NFL regular season and playoffs. In the regular season, a game may end in a tie if the score is still tied at the end of overtime. There is only a single 10-minute period of overtime, in which both teams get a chance to be on offense-unless a touchdown is scored. Once both teams have possessed the ball, sudden death scoring is in effect, where a safety, field goal, or touchdown will win the game.
IMPORTANT: If the first team on offense scores a touchdown or concedes a safety, the game immediately ends without the second team having a chance to possess the ball.
Both teams get two timeouts each during overtime, and there are no coach challenges. There are no PATs in NFL overtime because a touchdown ends the game; there is no need for an extra point or 2-point conversion.
Each overtime period lasts two possessions. Both teams get a chance to be on offense. The team that scores the most points during their possession is the winner. When on offense, a team gets the ball on their opponent's 25-yard line. Kickoffs are not used in college football overtime.
IMPORTANT: The order of which team is on offense first alternates each overtime period.
Teams will alternate playing offense when:
In college overtime, there are advantages and disadvantages to choosing offense or defense. Some teams like choosing defense first because they will know how much they will need to score once they are on offense. Others like playing offense first because scoring first will put pressure on the opponent's offense to do the same.
