The game hasn't even ended yet, and the Post-Gazette's Seth Rorabaugh already has a scoop:
According to a source with the NHL, the league's Department of Player Safety, which oversees supplemental discipline, will review the hit.
Good thing, it was a bad hit and clearly to the head. The play went unpenalized during the game, which happens away from the play in the fast moving NHL world. Refs can't track everything and that was a sneaky move by Suter.
It remains to be seen what Suter will get, the standard seems to be a two game suspension for first time offenders for hits to the head. Suter, also is a star player and Downie is far from it. It'll be interesting to see if that factors in. Hopefully Downie won't end up too injured, he stayed down and looked disoriented after falling to the ice.
