VIDEO: Brooks Orpik pastes Sean Couturier into end boards from behind

Midway through the second period in the battle of Pennsylvania Saturday afternoon, Penguins defenseman Brooks Orpik came away without penalty after this malicious hit on Flyers forward Sean Couturier, who was fortunately unscathed. 

Orpik appeared to be steering Couturier toward the endboards before giving his check an abrupt shove, causing the Flyers forward to land head-first into the glass.

Orpik escaped infraction but he may not survive sanction, as the NHL will most certainly have a look.
