hitting on arms during rebound

[ysong]

Thanks Jurassic Referee for clarifying this.

If the player owns his vertical space and he is entitled the right to raise his arms in this space to initiate contact without penalty, does that means a shooter is allowed to raise his non-shooting arm *within his vertical plane* to fend off defender's blocking arm?

the NCAA rules does not mention "vertical right" at all in this artical:

Personal Fouls
Section 18. By Players
Art. 5. A player shall not use the forearm and hand to prevent an opponent from attacking the ball during a dribble or when trying for goal.

Thanks.
