The Bruins will be without the services of defenseman Mark Stuart for for the next 4-6 weeks after fracturing a bone and dislocating a joint in his right ring finger in last night's 3-2 overtime win over the Buffalo Sabres.

Bruins GM Peter Chiarelli released the following statement late Wednesday afternoon:

Mark sustained a fracture to the 4th metacarpal of his right hand (ring finger) and dislocated his 4th metacarpal phlangeal joint. He was evaluated by Dr. Matt Leibman at Newton-Wellesley Hospital and is expected to miss approximately 4-6 weeks.

The Bruins are usually very tight-lipped about details of of player's injuries, so it is odd to see such an in-depth description of the injury.

In wake of Mark Stuart's injury, the Bruins have called up defenseman Steven Kampfer from the Providence Bruins. The 22-year-old former Michigan Wolverine is in his first pro season. He has posted 16 points (3-13-16) in 20 games for the P-Bruins this season with a +10 rating and 10 PIMs.

Kampfer was one of the young prospects that really impressed the Bruins staff during training camp. With the injury to Mark Stuart and Matt Hunwick now wearing a Colorado Avalanche sweater, Kampfer has a great opportunity to showcase his game at the NHL level.
