Time outs in league matches

The time out during our game with Sitting Ducks was necessary (serious injury).

Think about how we play throw in games; someone gets injured, we stop until they're okay and then we start again. It's essentially a time-out and we don't limit how many times we do it in a game. Why would we not apply the same instinctual consideration and logic to league games?

Yeah, but what about the mechanicals? I don't like unnecessary rules, but I like arguments during games and mob rule even less.
