Directing Player to Leave Game

[vawils]

In a game the other night a minor scuffle arose with some words exchanged and minor pushing and shuffing after a routine whistle. No technicals were assessed although possibly could have been. One coach immediately took out one of the offending players and demanded that a player from the other team who also pushed be taken out. There were only 18 seconds to go in the half. I asked the other coach to take the player off the court and the coach refused. He said he hadn't done anything wrong. He admitted he retaliated after the other player did something. I indicated I wanted him out for the remainder of the half and was not assessing a foul. He continued to state that he did not have to remove him and that there was no rule saying he had to. I told him I wanted to keep something else from happening or to give a technical and to diffuse the situation. He finally relented but I realized I was not sure if I could make him remove the player by the rules particularly without assessing a foul etc. By the way we talked to both coaches to start the second half and things went ok., Any thoughts?
