Jordan Staal Sucker punches Brandon Prust

So how many game suspension does Jordan Staal get for punching Brandon Prust? Does Brandon Prust embellish the hit at all? It will be interesting to see what kind of suspension the Colin Campbell "Wheel of Justice" rules. One could make the argument that Brandon Prust tries to take off Kennedy’s head off, then throws an elbow at Staal. Was the punch warranted. It's looks like a very questionable play in my opinion.
