New York Rangers center Derek Stepan had surgery to repair a broken jaw that he sustained following a hit by Montreal Canadiens left winger Brandon Prust during Thursday night's Game 3 of the Eastern Conference finals.
Rangers coach Alain Vigneault made the announcement Friday.
Also on Friday, Rangers forward Daniel Carcillo was suspended 10 games by the NHL for making physical contact with an official following the incident involving Stepan and Prust.
Prust was not penalized for the first-period hit but was scheduled for a hearing with the league Friday. He also could be suspended.
Vigneault was upset about the non-call Friday and lamented the officiating when discussing Stepan's injury and the incident that ensued, which resulted in a suspension for Carcillo. Carcillo was tossed from the game for elbowing linesman Steve Driscoll, who was trying to separate Carcillo from post-whistle action involving Prust.
Carcillo was automatically suspended by the league under Rule 40.3 pertaining to physical abuse of an official.
At 14:09 of the first period, Carcillo physically applied force to Driscoll while being escorted to the penalty box, the league said in a statement. Rule 40.3 Physical Abuse of Officials -- Category II states: "Any player who deliberately applies physical force to an official in any manner (excluding actions as set out in Category I), which physical force is applied without intent to injure, or who spits on an official, shall be automatically suspended for not less than 10 games."
Stepan had X-rays Thursday night, and he returned to the game after they were negative. He was in pain after the game and on Friday morning, according to the team. Montreal won the game 3-2 in overtime.
The jaw fracture was revealed after further tests were taken during a visit with a specialist.
Vigneault said Stepan's playing status for the remainder of the series will be determined by Saturday. Game 4 of the series is Sunday. The Rangers lead it 2-1.
"Yesterday there was an incident where Prust hit Stepan. That incident, obviously, four referees missed the call. Stepan is injured," Vigneault said. "Same player that called (Chris Kreider's) hit on (Habs goaltender Carey Price) an 'accidental but on-purpose' late hit, everything you want to get out of the game, that was his hit on Stepan.
"What saddens me about that hit is if the call is made on the ice, we're on a five-minute power play, and what happened to Dan Carcillo -- what he did was inexcusable and he's going to pay a big price for it -- if the call is made on the ice, he's not put in that position."
