Patrice Bergeron  took a hit from Philadelphia’s Claude Giroux with 17:30 remaining in the third period of Friday’s Game 4 win over Philadelphia. He did not return and his status for the start of the Eastern Conference finals against Tampa Bay is unknown at this point.
While the Bruins didn’t release any information on the particulars of the injury, it appeared that Giroux’s shoulder made contact with Bergeron’s head. Bergeron slowly skated off the ice on his own power to finish his shift but didn’t return.
“I don’t know. I have no update for you guys right now,” Bruins coach Claude Julien  said. “Basically, I can’t give you anything more than that.”
Bergeron leads the Bruins with 12 points in 11 playoff games. The Bruins will play Games 1 and 2 at home this week against Tampa Bay, with the series possibly starting Tuesday or Thursday at TD Garden.
Chris Kelly  stepped up from his third-line duty to center the Marchand-Recchi line for the remainder of the third period Friday.
“We talked about this morning, somebody asked me about different scenarios, and Chris Kelly is a very reliable player, a lot like Bergeron,” Julien said. “And a great two-way player. He as put up some decent points and he has also been extremely reliable defensively. So it’s an easy fit there and even Soupy [Gregory] Campbell has been a good player for us as well.
“He competes hard and very reliable. So you are able to move guys around and know they are going to do the job. And we’ve talked about our fourth line being a good line for us. And they have been good enough, to move them up to spots when need be,” Julien said. “Dan Paille took a shift there too on one of those lines. You have to be able to move guys around and they did a great job of stepping in and filling in those voids.”
