There was a lot of euphoria after the Bruins' Game 4 victory and sweep of the Philadelphia Flyers last night, but plenty of fingers were crossed, too.

Patrice Bergeron, the team's best all-around player during these playoffs, took a heavy and high hit from Flyers forward Claude Giroux with a little more than two minutes gone in the third period last night. Bergeron got up slowly and made his way to the bench without play being stopped. But when he reached the bench area, he headed straight down the runway to the team's locker room. He did not return.

After the game, Bruins coach Claude Julien said he hadn't heard anything yet on his center's status.

"I have no update for you guys right now," said Julien. "I can't give you anything more than that."

Bergeron nearly had his career ended when he suffered a severe concussion at the hands of former Flyers player Randy Jones in October 2007. Bergeron missed the rest of the season and suffered another concussion midway through the following season.
