A few years ago, I had a game in which a kid fell down hard so I stopped play. The coach ran right out before I could beckon him. The kid was fine and I told the coach he either had to come out or the team had to take a timeout. The coach said that since he wasn't "called out", it didn't count and the kid could stay in without the timeout. I replied that if that was the way he wanted it, I would then rule that he came onto the floor without being beckoned and it would be a technical - his choice.
He took the timeout.
