Stop game for injured player or not?

[dacodee]

Hello,

Boys Varsity game... Score is tied at 42, with just under 1 minute. White A1 attempts a 3. Teammate, A2 (with two left feet ) falls to the floor. Teammate, A3 attempts to box out opponent B1. Shot is missed and team B gets the rebound to attempt a fast break. Once the rebound is obtained by team B, I notice that A3 is continuing to back B1 down, so that B1 can fall over A2, who is still on the floor. B1 jumps over A2 and A3 falls over teammate, A2. Since I see that team B may have an opportunity to score on a fast break, I do not whistle for A3 pushing B1. For whatever reason, team B doesn't finish the fast break and pulls it out. Coach of team A yells, "stop the game, my player is hurt". I immediately blow my whistle to stop the game . I turn and ask the coach, "Who's injured?" He points to player A3, who fell over A2. Now I have coach of team B all over me. He's saying, "You can't do that!!! I'm making a move to the basket". I turn to team B coach and simply say, "Safety first, coach". Needless to say, team B won the game and it didn't come up since.

Here's the question... Would you have stopped the game when the coach tells you that someone is injured? Why/Why not???

Thanks
