Kampfer/By S. Bradley

Bruins general manager Peter Chiarelli today confirmed that defenseman Steven Kampfer suffered a knee injury Saturday in Springfield while playing for the Providence (AHL) farm club.

Chiarelli said the rookie will be re-evaluated this week but he also estimated that Kampfer would miss around two weeks of action.

Kampfer had been scratched for nine of Boston’s 10 games prior to his assignment to the P-Bruins for conditioning.

That would leave veteran Shane Hnidy, who skated in just three regular-season games, as the Bruins’ seventh defensemen when they start their first-round playoff series with Montreal Thursday. Chiarelli also mentioned Matt Bartkowski, Andrew Bodnarchuk and Colby Cohen as potential call-ups should the defense corps be struck by injuries.

Chiarelli conceded that Hnidy, who signed as a free agent in February, has “been a little rusty.” But the GM was optimistic Hnidy’s experience and leadership could help the Bruins if needed.
