The Bruins announced Friday that they have recalled defenseman Matt Bartkowski from Providence on an emergency basis. The news comes on the same day that defenseman Steven Kampfer was diagnosed with a mild concussion. With Andrew Ference also on the mend due to a lower-body injury, the B’s found themselves with only five defensemen prior to the call-up.

Bartkowski, a native of Pittsburgh, has played two games in his NHL career, and coincidentally, both have been against the Penguins. The Bruins host the Penguins Saturday night.
