SECTION 3. BLOCKING
Article 1 - Blocking
a. Blocking is obstructing an opponent by intentionally contacting the opponent with any part of the blocker’s body.
b. Pushing is blocking an opponent with open hands.
Article 2 - Below Waist
a. A block below the waist is a block in which the force of the initial contact is below the waist of an opponent who has one or both feet on the ground. When in question, the contact is below the waist (Rule 9-1-6).
b. A blocker who makes contact above the waist and then slides below the waist has not blocked below the waist. If the blocker first contacts the opposing player’s hands at the waist or above, it is a legal “above the waist’’ block (Rule 9-1-6).
Article 3 - Chop Block
Article 4 - Block in the Back
a. A block in the back is contact against an opponent occurring when the force of the initial contact is from behind and above the waist. When in question, the contact is at or below the waist (see Clipping, Rule 2-5) (Rule 9-3-5) (A.R. 9-3-3-I-VII and A.R. 10-2-2-XII).

SECTION 4. CATCH, RECOVERY, POSSESSION
Article 1 - Possession
Possession refers to custody of (a) a live ball as described later in this article and (b) a dead ball to be snapped or free-kicked. It may refer either to player possession or team possession.
a. Player Possession.
The ball is in player possession when a player has the ball firmly in their grasp by holding or controlling it with hand(s) or arm(s) while contacting the ground inbounds.
b. Team Possession.
The ball is in team possession:
1. When one of its players has player possession, including when they are
attempting a punt, drop kick or place kick; or
2. While a forward pass thrown by a player of that team is in flight; or
3. During a loose ball if a player of that team last had player possession;
or
4. When the team is next to snap or free kick the ball.
c. A team is in legal possession if it has team possession when its players are eligible to catch or recover the ball.
Article 2 - Belongs to
Article 3 - Catch, Interception, Recovery
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.
Article 4 - Simultaneous Catch or Recovery
SECTION 5. CLIPPING
Article 1
a. Clipping is a block against an opponent in which the force of the initial contact is from behind and at or below the waist (Rule 9-1-5).
b. The position of the blocker’s head or feet does not necessarily indicate the point of initial contact.

a. A pass is forward if the ball first strikes the ground, a player, an official or anything else beyond the spot where the ball is released. All other passes are backward passes. When in question a pass thrown in or behind the neutral zone is forward rather than a backward pass.(Exception: Games using Instant Replay)
b.
