Corey Tropp is out indefinitely with a broken jaw suffered during a fight last weekend.
Tropp is expected to miss at least five weeks after undergoing surgery. Tropp also suffered a concussion.
Tropp fought with Jamie Deavne in the third period on Sunday.
A full line brawl occurred before the next faceoff, when Buffalo Sabres' enforcer John Scott went after Toronto's Phil Kessel.
The brawl led to 211 penalty minutes and three ejections.
