a. To catch a ball means that a player:
1. Secures firm control with the hand(s) or arm(s) of a live ball in flight before the ball touches the ground, and
2. Touches the ground inbounds with any part of the body, and then
3. Maintains control of the ball long enough to enable that player to perform an act common to the game, i.e., long enough to pitch or hand the ball, advance it, avoid or ward off an opponent, etc., and
4. Satisfies paragraphs b, c, and d below.
b. If a player goes to the ground in the act of catching a pass (with or without contact by an opponent) the player must maintain complete and continuous control of the ball throughout the process of contacting the ground, whether in the field of play or in the end zone. This is also required for a player attempting to make a catch at the sideline and going to the ground out of bounds. If the player loses control of the ball which
then touches the ground before they regain control, it is not a catch. If the player regains control inbounds prior to the ball touching the ground it is a catch.
c. If the player loses control of the ball while simultaneously touching the ground with any part of their body, or if there is doubt that the acts were simultaneous, it is not a catch. If a player has control of the ball, a slight movement of the ball, even if it touches the ground, will not be considered loss of possession; the player must lose control of the ball in order for there to be a loss of possession.
d. If the ball touches the ground after the player secures control and continues to maintain control, and the elements above are satisfied, it is a catch.
e. An interception is a catch of an opponent’s pass or fumble.
f. A catch by any kneeling or prone inbounds player is a completion or interception (Rules 7-3-6 and 7).
g. A player recovers a ball if they fulfill the criteria in paragraphs a, b, c, and d for catching a ball that is still alive after hitting the ground.
h. When in question, the catch, recovery or interception is not completed.
