Very early (like 25 seconds into the first period early) in last night's Maple Leafs/Senators game, Toronto's Frazer McLaren had a score to settle with Ottawa's David Dziurzynski. The fight barely lasted shorter than then game had at that point and when it was all over, Dziurzynski got knocked the eff out and was face down on the ice. He did not return to the game as he had been concussed in the fight.
