Source: Sturm's injury significant

BOSTON -- Bruins forward Marco Sturm, who left Boston's playoff game against Philadelphia in the opening period after apparently hurting his right leg, suffered a significant injury and likely will miss the rest of the season, according to a team source.

After Boston's 5-4 overtime victory, Bruins coach Claude Julien said he did not have an update on Sturm.

"Not yet," said the coach. "He's being evaluated. We'll have something more specific for you guys by tomorrow."

Sturm went to the ice in the Flyers' zone in the opening minute and remained there while play continued at the other end. At the whistle, a Bruins trainer came on and Sturm eventually got to his feet. He skated off, but favored his right leg.

Sturm scored the game winner in overtime of the Winter Classic against the Flyers at Fenway Park, but did not register a point in the team's first-round series against the Sabres.
