Fair Catch
ARTICLE 1.
a. A fair catch of a scrimmage kick is a catch beyond the neutral zone by a Team B player who has made a valid signal during a scrimmage kick that is untouched beyond the neutral zone.
b. A fair catch of a free kick is a catch by a Team B player who has made a valid signal during an untouched free kick.
c. A valid or invalid fair catch signal deprives the receiving team of the opportunity to advance the ball. The ball is declared dead at the spot of the catch or recovery. If the catch precedes the signal, the ball is dead when the signal is first given.
d. If the receiver shades their eyes from the sun without waving their hand(s), the ball is live and may be advanced.
