David Backes, involved in a crash on Saturday with Ottawa forward Scott Sabourin that sent the latter to the hospital, is likely to miss the Bruins’ next two games, at least.

Coach Bruce Cassidy pegged Backes as “doubtful’’ to play Monday against Pittsburgh and Tuesday in Montreal, but he did not have more detailed information on Backes’s condition. The club announced that Backes has an undisclosed upper-body injury.

“It was a pretty good collision,’’ Cassidy said. “Like everybody, he was a little rattled by everything that transpired. Let’s just see how he’s doing tomorrow and go forward from there. It’s hard for me to say until the exact injury is determined.’’
