Bruins' Dennis Seidenberg to miss eight weeks after back surgery

The Boston Bruins will be without Dennis Seidenberg for eight weeks after he undergoes a lumbar microdiscectomy Thursday morning. The surgery will repair a lumbar spine disc herniation, according to GM Don Sweeney.

Last week, Sweeney announced that the 34-year old Seidenberg would not be on the ice and would be limited at the start of training camp. Team trainers were taking a day-by-day approach to a reported upper-body injury for the defenseman.

With Dougie Hamilton or Matt Bartkowski gone, will Sweeney go out and look to bring in a short-term solution to help his defensive depth?

Seidenberg, who played all 82 games last season after being limited to only 34 in 2013-14, joins Seth Griffin on the injured list after the forward suffered an MCL injury that will sideline him for 3-4 weeks.

Including this season, Seidenberg has three more years left on his deal, and with Zdeno Chara turning 39 in March, now is a good time for Sweeney and the Bruins to evaluate their young defensemen and see how they respond to the added responsibilities.
