Grant time-out for "injured" player?

[rainmaker]

So Team A player with heart problem was fine until Team B had the ball??

Hmmmm...

If there's no advantage to be gained by Team A in stopping the game, I suppose you might stop the game, and then decree that Team A player with heart problem can't come back into the game without a doctor's note. But really, why's this guy playing, anyway?

And why's he still trying to play if he can't breathe? He should hold back behind the play, and lean over or flail around or fall down or something so that it's obvious he's "injured".
