Walk-off touchdown

A walk-off touchdown is a touchdown scored in gridiron football that ends the game with the winning team being either behind or tied in points at the beginning of the play.

This is considered the most spectacular and rare play during regulation time happening in the 4th quarter when the winning team is losing at the beginning of the play as opposed to being tied. The play clock must say :00 at the end of the play in the 4th quarter & it must be the last play of the game.

A walk-off touchdown is much more common during overtime play because of the overtime rules in effect.

Former quarterback Tim Couch has the most walk-off touchdowns from throwing Hail Marys in the NFL with two.
