Training Camp is not even a week old, yet the Boston Bruins have been hit hard by injuries. First, Seth Griffith suffered an MCL sprain in the pre-season opener against the Devils and will miss 3-4 weeks. A few days later, GM Don Sweeney announced that defenseman Dennis Seidenberg will have surgery for a herniated disc in his back and will miss approximately eight weeks.

The injury couldn’t have come at a worse time for Seidenberg, who was looking to have a bounce-back season in 2015-16. The German blue-liner tallied 17 points (3 goals, 14 assists) and played in all 82 games in 2014-15 — a year after he suffered a knee injury in December that ended his 2013-14 season — but his uncharacteristic struggles in his own end led to one of his worst seasons in Black and Gold.

With Seidenberg out, the battle to make the opening night roster just heated up for some of the Bruins defensemen. Guys like Joe Morrow and Colin Miller now have the opportunity to prove they belong as Training Camp progresses.

Sweeney will have a press conference after the first training camp session on Wednesday to address the media on Seidenberg’s surgery and timetable.
