This is probably going to depend on Juwan's relationship with admin/team. If there was any other history/negative track record, he's probably gone. If this is really out of character for him, he's suspended several games and invited back. He was wrong at basically all levels on this one and it caused players to start fighting. You can't sweep this under the rug and just move onto the next game.
The only thing that can be swept under the rug in college hoops is outright cheating in recruiting.
Yeah, I don't actually think he'll be fired, but UM has got personality problems with both of its revenue producing coaches. If he had punched a player he'd already be gone though.
There was also the time he knocked over the trash can after losing the national championship game.
