Stop Game for Injury?

[johnnyrao]

Boys V game last night. Home is down by 4 with about 1 minute left. I am C. A1 takes a shot and misses. Aw rebounds and as he is prepping to take a short shot I see A3 direclty under the basket, on his stomach and holding his head and face (not moving much). I blew the whistle as A2 was beginning to shoot but had not released the ball. A3 was okay after a few minutes (took a hit to the face) but he went out because Coach A came on the floor. Since A2 had not released the ball we gave A the ball inbounds. Neither coach had any complaint about it.

Would you stop the game at this point or wait until A2 shoot since A is down by 4? My opinion was that A3 was in a very vulnerable position especially if the shot is missed and a big rebound scramble ensues. Also, he was holding his face so i didn't know exactly what was wrong. Also, did we administer it correctly in giving the ball back to A?
