Bergeron/By S. Bradley

WILMINGTON, Mas. — Bruins head coach Claude Julien said after practice today neither Steven Kampfer or Patrice Bergeron will be available against Pittsburgh Saturday at TD Garden.

Neither player practiced with the team today at Ristuccia Arena.

Kampfer suffered a “mild” concussion last night against Tampa Bay and could be ready to return in about a week, according to Julien. The rookie defenseman was rocked in the second period by a Mattias Ritola hit and didn’t play in the third period.

Bergeron left the club for “personal reasons.” Julien said the center had to travel to attend to the matter and would not be back for Saturday’s game with the Penguins.

While the Bruins are set at forward with 12 healthy bodies, they will require a call-up from the Providence (AHL) farm club on defense.
