6-5-6 Team R has three options if team K commits kick catching interference: the result of the play, an awarded fair catch after enforcement of a 15-yard penalty from the spot of the foul, or a 15-yard penalty from the previous spot and a replay of the down (as seen in the MechaniGram). The first option would only be chosen if team R advanced the ball farther than the penalty. The second serves as a remedy for a short return or a muff or fumble recovered by team K. It also allows for team R to attempt a free kick if the penalty moves the ball close enough to team K’s goalline for a field goal attempt.
6-5-6 A fair catch is when the receiver gives up his right to advance in exchange for freedom from contact by the opponent. One potential catch (pardon the pun) to the deal may be a muff on the part of the receiver. In PlayPic A, the receiver has given a valid fair catch signal, then muffs the ball (PlayPic B). The receiver’s fair-catch interference protection ends when he muffs the kick.
6-5-6 Kick-catching interference. R has the option of taking the results of the play, accepting an awarded fair catch at the spot of the foul, accepting a 15-yard penalty from the spot of an awarded fair catch, or replaying the down after having the penalty enforced from the previous spot.
6-5-6 It is kick-catching interference when the kickers touch a free kick in flight. It makes no difference whether or not the ball has been beyond the receiver's free-kick line. This restriction ends after a receiver touches the kick. R may choose an awarded fair catch at the spot of the foul with a 15-yard distance penalty or have the distance penalty enforced from the previous spot and rekick.
