They deemed it shoulder height. Pretty tight call if you ask me.
Well unfortunately for Iowa, that is the rule; his hand was (slightly) above his shoulders.......
Section 2 Fair Catch
DEFINITION
Article 1 A Fair Catch is an unhindered catch of an airborne scrimmage kick that has crossed the line of
scrimmage, or of an airborne free kick, by a player of the receiving team who has given a valid fair catch
signal.
FAIR CATCH SIGNAL
Article 2
Item 1: Valid Fair-Catch SignalA fair-catch signal is valid if it is made while the kick is in flight by a
player who fully extends one arm above his helmet and waves it from side to side. A receiver is
permitted to legally raise his hand(s) to his helmet to shield his eyes from the sun, but is not permitted
to raise them above his helmet except to signal for a fair catch.
Item 2: Invalid Fair-Catch. If a player raises his hand(s) above his shoulder(s) in any other
manner, it is an invalid fair-catch signal. If there is an invalid fair-catch signal, the ball is dead when
caught or recovered by any player of the receiving team, but it is not a fair catch. (The ball is not dead
if it touches an opponent before or after it strikes the ground. See Article 3b).
Note: A fair-catch signal given behind the line of scrimmage on a scrimmage kick is ignored and is neither valid
nor invalid.
Penalty: For an invalid fair-catch signal: Loss of five yards from the spot of the signal.
Item 3: Muff. After a valid fair-catch, the opportunity to catch a kick does not end if the ball is
muffed. The player who signaled for a fair catch must have a reasonable opportunity to catch the
muffed ball before it hits the ground without interference by members of the kicking team, and
regardless of whether the ball strikes another player or an official.
Penalty: For interference with the opportunity to make a fair catch after a muff: A fair catch is awarded at the spot of the interference even if the ball is not caught.
Item 4: Intentional Muff. An intentional muff forward prior to a catch in order to gain ground is an illegal
bat (see 12-1-8).
Item 5: Illegal Block. Until the ball touches a teammate or an opponent, a player who makes a valid or
invalid fair-catch signal is prohibited from blocking or initiating contact with a player of the kicking
team.
Penalty: For an illegal block after a fair-catch signal: Loss of 15 yards from the spot of the foul.
