It's the news we were all fearing: the Bruins announced today that Patrice Bergeron will be out long term.
From the team:
"Patrice Bergeron sustained a rib and sternoclavicular injury during the second period of the Bruins vs. Stars game on November 16 in Dallas."
"The sternoclavicular joint or sternoclavicular articulation is the joint between the manubrium of the sternum and the clavicle bone. It is structurally classed as a synovial saddle joint and functionally classed as a diarthrosis and multiaxial joint."
This makes it sound like it was, in fact, in the shoulder-ish area.
The Bruins recalled Colby Cave from Providence as well, filling Bergeron's roster spot.
