BOSTON — Bruins head coach Claude Julien confirmed this afternoon what everyone suspected and some reported about winger Marco Sturm: he’s out for the season with a knee injury.

About an hour later, the official press release declared Sturm’s season done because of a torn ACL and MCL. He will have surgery in the next four to six weeks and then need six months time to recover. That means he’s highly unlikely to be available to start next season.

Sturm injured his right knee on the first shift of the Bruins’ Game 1 victory Saturday at TD Garden against Philadelphia. Julien said that right now there’s no update on whether he will require surgery.

The Bruins’ leading goal-scorer during the regular season, Sturm was mired in a one-goal-in-23-games slump before the injury.

“Sturmy brings a lot to our hockey team, obviously,” center Marc Savard said. “A lot of speed, he was our top goal-scorer ths year, a great penalty-killer, a fierce guy; he works hard every time. He’s certainly going to be missed right now. We’ll have to try and fill that void like we filled all year.”

Sturm missed most of last season after surgery on his left knee and rehabbed all summer to make it back this year. Next year will be the final year of his contract with Boston.

Forward Vladimir Sobotka, who also suffered an injury but returned to the game Saturday, was deemed “OK” by Julien.
