Boston Bruins

The Bruins may have dodged a bullet with defenseman Matt Grzelcyk, who exited Sunday’s loss to the Penguins with an obvious arm injury, according to Bruins head coach Bruce Cassidy.

That belief comes after X-rays on the Charlestown, Mass. native came back negative, leaving the B’s to simply wait and see if there’s any tissue or ligament damage to Grzelcyk.

“Too soon to tell if there’s soft tissue damage or something else in there,” Cassidy told reporters after the loss. “Right now, that’s good news. I would guess tomorrow we’d have a better idea going forward.”

Hit by Penguins forward Patric Hornqvist along the Boston boards, the 25-year-old immediately fell down to the ice and grabbed at his arm. Helped off the ice and back to the Boston locker room, it would be the last the B’s saw of No. 48 that night, as the team quickly ruled him out for the remainder of the night with an upper-body injury.

“I hope he heals quickly,” Cassidy said of the 5-foot-9 defender. “To think he’ll turn around in 48 hours might be a little too optimistic, to be honest with you.”

If Grzelcyk is unable to go Tuesday night in Columbus, it’s likely that Steven Kampfer will slide into the mix.

Kampfer has not played in an NHL contest since Dec. 23.
