David Backes (upper-body) considered "doubtful" for next two games

A downright terrifying incident at TD Garden on Saturday appears to have impacted more than the Sens' Scott Sabourin, as the Bruins are expected to be without veteran forward David Backes for at least the next couple of games.

"Probably get a better evaluation [Monday],” B's coach Bruce Cassidy said following Sunday's practice at Warrior Ice Arena. “I would say right now he’s doubtful for the next couple games. But I think [Monday] we’ll have a better determination."

Knocked out of play 34 seconds into the game, Backes' departure came on the heels of a collision with Sabourin that left the Ottawa grinder unconscious and ultimately stretchered off the Boston ice. It was a hit that certainly appeared to impact Backes as a person, too, with No. 42 looking visibly distraught at the scene unfolding in front of him.

"It’s an upper-body injury," Cassidy offered. "It was a pretty big collision."

The "upper-body" designation is common in today's game, but it does lead to extra wincing knowing the 35-year-old forward's (unfortunately detailed) concussion history, though Cassidy wouldn't specifically touch on that in his talk with the media.

"The level of concern would be the same for anybody if you get hit that hard," said Cassidy.

Backes, who is in the fourth year of a deal that comes with a $6 million cap hit, has appeared in eight games for the Bruins this season, with one helper and 13 shots to go with 14 hits for Cassidy's squad.

The Bruins will have a back-to-back beginning Monday at home against the Penguins, and ending Tuesday night in Montreal.
