San Jose Sharks forward Mason Marchment has been fined $5,000, the maximum allowed under the NHL’s collective bargaining agreement, for roughing New York Islanders forward Victor Eklund during Monday’s game at SAP Center, the league’s Department of Player Safety announced Tuesday.

The incident happened at 8:52 of the third period of the Sharks’ 3-2 win. Marchment was assessed a double-minor for roughing. The fine money goes to the Players’ Emergency Assistance Fund.

Sportsnet reported that the scrum started after Eklund hit Sharks forward Kiefer Sherwood from behind and was not penalized, and that Marchment then threw several bare-knuckle punches at Eklund. It was Marchment’s first fine this season and the fourth of his eight-year career, Sportsnet said. He has 20 penalty minutes this season. The league’s announcement did not say whether he would miss any time; Sportsnet treated the discipline as a fine only, leaving him available for the Sharks’ next game, Wednesday night against the Pittsburgh Penguins at SAP Center.
