Hockey is one of the most physical sports, and referees try to keep it in line by assessing penalties when a push or a trip goes too far.
But on Monday night in Ottawa, the officials had enough.
After a fight broke out in the third period of a roughly played game between the Florida Panthers and the Ottawa Senators, the officials threw up their hands and kicked every skater on the ice out of the game.
Florida was leading by 4-0 when Brady Tkachuk, the Senators captain, came off the bench and got a quick breakaway.
The officials at first seemed to get the situation under control, but a punch heated things up again.
