The penalty for all screening fouls in this section are as follows:

PENALTY—Live-ball foul. Five yards. [S33]

Screen Blocking

ARTICLE 1. The offensive screen block shall take place without initiating contact. The screen blocker shall have their hands and arms at their side, behind their back, or against their chest when screen blocking. A player must be on their feet before, during, and after screen blocking. A blocker may use their hand or arm to break a fall or retain their balance.

Screen Blocking Fundamentals

ARTICLE 2. A player who screen blocks shall not do any of the following:

a. Take a position closer than a normal step when behind a stationary opponent.
b. Make contact when assuming a position at the side or in front of a stationary opponent.
c. Take a position so close to a moving opponent that their opponent cannot avoid contact by stopping or changing direction. The speed of the player to be screened will determine where the screener may take their stationary position. This position will vary and may be 1 to 2 normal steps or strides from the opponent.
d. After assuming their legal screening position, move to maintain it, unless they move in the same direction and path as their opponent.

Illegal Screen Blocking

ARTICLE 3. Any use of the hands, arms, elbows, legs, or body to initiate contact during an offensive player’s screen block is illegal. It is a foul if the blocker creates contact by violating any of the screen blocking fundamentals in Rule 9-3-2.

Blocking and Interlocked Interference

ARTICLE 4. Teammates of a runner or passer may interfere for them by screen blocking but shall not use interlocked interference by grasping or encircling one another in any manner.
