B's lose defensive depth with Kampfer injury

The Bruins' Steven Kampfer, who has spent time this season with both the Boston team and it's AHL affiliate in Providence, injured his knee in a game in Springfield on Saturday and won't be available as a depth defenseman in the first round of the playoffs that begin Thursday against Montreal. He's expected to be out up to two weeks.

The Bruins sent Kampfer to Providence last week to give the frequent healthy scratch some playing time.

"Steven injured his knee and is going to be evaluated in the next couple of days," general manager Peter Chiarelli said in a conference call Monday. "My guess is he'll be gone for at least two weeks."

Chiarelli didn't seem too concerned about depth on the blue line, noting players the team could call up from the "Black Aces" -- the taxi squad NHL teams use with their AHLers during the playoffs.

"We've got depth beyond that in [Matt] Bartkowski, [Andrew] Bodnarchuk and [Colby] Cohen. We've got some players that can fill in," Chiarelli said. "Obviously, it's a blow to our depth, but from what I'm told, it's not that bad. I can't give you an exact time frame, but I know it's at least two weeks."

Chiarelli also confirmed that goalie Anton Khudobin and center Zach Hamill will be part of the "Black Aces" during the first round and practice with team.
