The NFL reworked its overtime rules in 2010 and the only difference between the regular-season application and the postseason application of the rules is that in postseason, obviously, a game cannot end in a tie.

That goes for the Super Bowl, too, even though an OT has never been needed in any of the previous 50 games.

From the NFL, here’s what happens in OT in the playoffs:

“The modified system of determining the winner shall prevail when the score is tied at the end of regulation for postseason NFL games. The system guarantees each team a possession or the opportunity to possess, unless the team that receives the opening kickoff scores a touchdown on its initial possession.

“At the end of regulation time, the Referee will immediately toss a coin at the center of the field in accordance with rules pertaining to the usual pregame toss. The captain of the visiting team will call the toss prior to the coin being flipped.

“Following a three-minute intermission after the end of the regulation game, play will be continued in 15-minute periods until a winner is declared. Each team must possess or have the opportunity to possess the ball unless the team that has the ball first scores a touchdown on its initial possession. Play continues in sudden death until a winner is determined, and the game automatically ends upon any score (by safety, field goal, or touchdown) or when a score is awarded by the Referee for a palpably unfair act. Each team has three timeouts per half and all general timing provisions apply as during a regular-season game. The try is not attempted if a touchdown is scored. Disqualified players are not allowed to return.”

If the score remains tied at the end of the period, the teams go to another overtime and play continues for as many periods as it takes to determine a winner. Each period has a two-minute warning and teams get three timeouts per half (two periods).

If the game goes to a third overtime, there is no intermission, but there is another coin toss and timeouts reset.

We’ll get back to you if the score remains tied after four overtimes.
