This is a long shot, but I'm hoping someone happened to see this.
On Sportsnet today, they showed a fight between two junior players, I assume the OHL b/c after the fight Kypreos was speaking with David Branch.
Anyway, the fight took place on the far side of the ice, in front of the bench (based on where the camera was) During the fight someone was KO'd and went down. The guy who threw the punch pulled away from the ref, show boating to the crowd and skating around etc.. which is a little odd as he showed no concern at all for the unconscious player.
He skated off to the other side of the ice, while still showing his pride in himself, through the doors and down a ramp into the dressing room I guess.
Sorry for the vague details but I assume it happened recently and I didn't get a chance to see much of it b/c the TV was far away and on mute.
