GIF: Curtis Glencross appears to injure knee while trying to hit Olli Maata

Curtis Glencross left Saturday's game against the Pittsburgh Penguins with what has been classified as a lower-body injury. 

Upon closer look, it appears as though he injured his knee on an attempted hit on Olli Maata, further compounded by Matt Niskanen getting knocked down onto the leg in question.

Glencross missed 15 games earlier this season after spraining the same knee.
