Seidenberg injury opens opportunity for Bruins defencemen

Watch as Toronto Maple Leafs fan Steve "Dangle" Glynn confront Boston Bruins forward Patrice Bergeron about the pain he inflicted on Leafs Nation in Game 7 back in 2013.

The Boston Bruins will open their season without a key defenceman.

Dennis Seidenberg will be sidelined approximately eight weeks, general manager Don Sweeney announced, after he undergoes a lumbar microdiscectomy scheduled for Thursday.

The surgery is to repair a lumbar spine disc herniation and will be performed by Dr. Louis Jenis at Massachusetts General Hospital.

Seidenberg, 34, is expected to make a full recovery.

“It’s definitely a setback, first and foremost, from Dennis’s standpoint,” Sweeney told reporters. “He’s worked hard. He came back from a [torn] ACL last year and has a setback, which we hope being identified fairly early in camp, trying to get some rest to let it calm down — wasn’t able to do that.

“So it’s definitely a setback. It’s obviously an opportunity for the other guys we were evaluating anyway amongst our D core, and we’ll go from there.”

Sweeney said that the Seidenberg sustained his injury during his own off-season training. The team was made aware on Monday.

“You know what? He apologized,” Sweeney said. “He’s a proud guy and a team member, and he takes that to heart. So he was apologetic, and said he’ll do what he can to get back, and that’s what you appreciate in a guy who cares.”

The Bruins’ blue line has been hampered in the last year by injuries and trades, but Seidenberg was a constant. He played all 82 games for Boston in 2014-15, scoring 14 points.

Seidenberg’s injury could open up a chance for young defencemen such as Colin Miller or Joe Morrow to crack the Bruins’ opening-night roster.
