In American football
, a two-point conversion
is an extra point
attempt where a team that has just scored a touchdown
starts a play
at the opponent's two-yard line and tries to cross the goal line. If the team succeeds they earn an additional two points on top of the six points for the touchdown.
The two point conversion rule was introduced to the NFL in 1994, but was an established rule of the American Football League since its inception, and has also been a long-standing rule of college football.
