"The fair catch kick is a rule at the professional and high school levels of American football that allows a team that has just made a fair catch to attempt a free kick[A] from the spot of the catch. The kick must be either a place kick or a drop kick, and if it passes over the crossbar and between the goalposts of the defensive team's goal, a field goal, worth three points, is scored to the offensive team."
