Vermette slapped his stick against the back of linesman Shandor Alphonso's legs after losing a faceoff to Minnesota Wild captain Mikko Koivu during the third period of the Ducks' 1-0 win Tuesday night.
Vermette had a disciplinary conference call with the league and the players' union Wednesday, but the NHL didn't issue an immediate confirmation of what's expected to be an automatic 10-game suspension under league rules for applying physical force to an official without intent to injure.
The normally mild-mannered Vermette appeared to act out of frustration when Alphonso dropped the puck before the forward had put his stick in place on the ice.
The officials immediately stopped the game and assessed a game misconduct to Vermette, who has been among the NHL's best faceoff men this season. Vermette has won 62.4
Vermette is allowed to appeal any suspension. NHL Commissioner Gary Bettman would hear the first appeal, followed by an independent arbitrator.
Vermette isn't known as much of a hothead, and he had been enjoying steady success in his first season with the Ducks, who signed the 34-year-old veteran to a two-year deal in August. Along with his remarkable faceoff proficiency, the 2015 Stanley Cup champion has contributed eight goals and 14 assists in 58 games.
After the game, Anaheim coach Randy Carlyle said he thought Vermette hadn't acted maliciously, but had been trying to get Alphonso's attention after what he viewed as an unfair faceoff. Alphonso is a former OHL player in his first full season as an NHL linesman.
If Vermette immediately serves an entire 10-game suspension, he would be out until the Ducks have just 14 games left in their regular season. He would be eligible to return for Anaheim's visit from the Washington Capitals on March 12.
Anaheim hosts the Florida Panthers on Friday. The Ducks recalled forward Corey Tropp from their AHL affiliate in San Diego during Vermette's disciplinary hearing.
Wideman was given an automatic 20-game suspension for deliberately attempting to injure an official, and Bettman upheld it before a neutral arbitrator decided Wideman's action hadn't been intentional and reduced the ban to 10 games.
Wideman incurred a concussion on a hit by Nashville's Miikka Salomaki moments before he hit Henderson, and Wideman claimed he didn't see Henderson on his way back to the bench. Henderson also incurred a concussion when Wideman hit him.
The arbitrator ruled that Wideman's suspension should be halved, but Wideman had already served 19 games of the ban. He was refunded his lost salary for the difference.
