rule interp: injured player & alternating poss.

[Ref in PA]

What do I think about? Player count, properly equipped, dunking, my IRA investments, what kind of dog will win "best in the show" this year ...

When I have a player shaken up, I will ask the player if he/she can continue. If not, I will beckon the coach. If the coach comes out on the floor without me calling for them, then we have a T situation.

The illegal screen is a foul. Does AP arrow change when a foul is called on a throw-in? No. You have to judge if the throw-in completed before the foul or not. If the throw-in completed before the foul, arrow gets changed, if the throw-in did not complete, the arrow stays the same.
