The fair catch kick rule states that, after a player has successfully made a fair catch or has been awarded a fair catch (as the result of a penalty such as kick catch interference), their team can attempt a kick from the spot of the catch.

Prior to the kick, the opposing team must be lined up at least ten yards beyond the spot of the ball. The kick itself can be either a place kick or drop kick; a kicking tee cannot be used.

Like other field goal attempts, the kicking team is awarded three points if the kick goes above the crossbar and between the goalposts of the opposing team's goal and did not touch a player of the offensive team after the kick. If the attempt fails, the opposing team is awarded control of the ball from the spot of the kick. The opposing team can also return the kick if it does not go out of bounds.
