Must see: Smith-Pelly crushes Penguins player

Washington Capitals Devante Smith-Pelly rocked Pittsburgh Penguins defenseman Brian Dumoulin with a hit that seems to be nothing but perfect, except for the fact that Dumoulin turned his back at the last second, instead of absorbing the hit. 

Dumoulin left for the locker room with the trainer, and he didn't came back. There is no official word on the nature of the injury, but it looks like it could be in the arm or the shoulder area.

More details to come...
