Pascal Dupuis, the Penguins’ first-line right winger, has a severe knee injury and could miss the rest of the regular season.

Coach Dan Bylsma updated Dupuis’ condition after the team’s game-day skate at PNC Arena.

He said Dupuis “will be going for ACL knee surgery in a couple of weeks and is out indefinitely. No timetable, but likely that (he) might be out for the remainder of the season. We’ll see more after the surgery.”

Dupuis was injured early in the first period of the Penguins’ 5-0 loss in Ottawa Monday, when linemate Sidney Crosby fell on his right leg after being checked by Senators defenseman Marc Methot.

Dupuis is the Penguins’ No. 6 scorer, with seven goals and 13 assists in 39 games.

In addition to working alongside Crosby and Chris Kunitz on the top line, Dupuis has been one of the Penguins’ top penalty-killing forwards, averaging one minute, 58 seconds of shorthanded ice time per game.

His place on the Penguins’ top line tonight against the Hurricanes will be taken by Joe Vitale, who filled in there after Dupuis was hurt.
