Offensive player goes up for jumper in paint and comes down wrong on ankle. Defense gets rebound and fast breaks. The ball and most players are 20 feet away from the injured player. The official blows whistle to stop play for injured player. In the past I've seen games where play doesn't stop until the injured players team regains possesion. Whats the right call. BTW, the player left briefly but did return and was able to play.
