Alexei Emelin wrecks Jason Spezza's face!

The Dallas Stars were in Montreal yesterday to play the Canadiens. During the game, Habs' defensemen Alexei Emelin got kicked out of the game with a 5 minutes major penalty and a game misconduct for boarding Jason Spezza from behind and cutting his nose open. Spezza had to get his face stitched up before returning to the game later. Do you think this is a suspendable hit? If so, how many games should he receive?
