Player has his own helmet used against him as a weapon! (VIDEO)

This was an absolutely insane incident in the NHL tonight. During the Panthers and Pengui9ns match up, Pittsburgh Penguin Kris Letang had his own helmet used against him as a weapon. Florida Panthers Willie Mitchell grabbed Letang's helmet during an altercation and started swinging it at Letang. I can't imagine what the NHL is going to do about this, but one has to think that Mitchell is going to find himself with a pretty serious suspension and fine following this one. You can see the play here in the video below.
