An NFL team may try an uncontested field goal after a fair catch

American Football is filled with strange and complex rules. For instance, after a fair catch - which is when the receiving team opts to receive the ball off of a kickoff without trying to run it back, accepting the spot of the catch - the receiving team may try for a field goal. On this particular field goal attempt, the team may try a field goal from the spot they received the fair catch and the opposing team is not allowed to try and block it. While this rule is rarely used, it does exist.
