Really, really weird. Did anyone see him take a shot to the leg, or go down hard? I don't remember seeing or hearing anything, but I was busy during most of the third period throwing my laptop against the wall because of a non-functioning trackpad, so I only sporadically watched the end of the WC.
The shift report isn't helpful. 13:14 TOI, played 5 minutes in the third, including the victory shift.

He must have Greg Campbelled himself for a good part of the game, or it's a "delicious pancake" off-ice injury.
