Bruins coach Claude Julien told reporters on Friday that defenseman Andrew Ference is dealing with an upper-body injury, explaining his absence in the third period of Thursday night’s 7-5 win over the Flyers.

Julien said that Ference is “very questionable” for Saturday’s game against the Penguins.

“We’re hoping it’s minor enough that we’ll see him back soon,” Julien said.

Given Ference’s status, the Bruins on Friday morning called up Matt Bartkowski on an emergency basis from Providence.
