NHLer driven head first into the boards from behind.

Gabriel Dumont may be hearing from the National Hockey League's Department of Player Safety after this hit.

The Tampa Bay Lightning center delivered a very questionable hit to New York Rangers defenseman Steven Kampfer, sending Kampfer head first into the boards at an ugly looking angle.

Kampfer lay hunched up against the boards for several moments before eventually getting back up to his feet, and while players from both teams pushed and shoved one another after the hit, nothing really came of it.
