Chicago Blackhawks forward Anthony Duclair left Saturday's game against the Boston Bruins following a collision with Brad Marchand midway through the first period.
Marchand hit Duclair up high while seemingly trying to avoid him, and Duclair's right leg appeared to buckle as he was falling.
The Bruins' talented agitator was assessed an interference minor, and Duclair was later ruled out for the rest of the game.
