Two-point conversion

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 has been a long-standing rule of college football, and was one of many professional football firsts featured by the American Football League during its existence, but the NFL did not adopt it until 1994.
