It could have been seen as a warning sign when Dennis Seidenberg didn’t participate in the scrimmage in his final day of captain’s practice, and now that has been confirmed. The 34-year-old German defenseman will be out for the first few days of main training camp for the Bruins with an upper body injury sustained while training the past week.

Bruins general manager Don Sweeney said that Seidenberg will be reevaluated in the next few days, and couldn’t predict how minor or serious the issue could be.

“The only issue we have right now is that Dennis Seidenberg will likely not skate for the next few days,” said Sweeney. “He reported to our trainers on Monday with an upper body injury from training. The doctors have chosen to take a conservative approach, and evaluate him day-to-day.”

Sweeney also confirmed that Seidenberg should be the only one of the 60 Bruins players in training camp that won’t be on the TD Garden ice once training camp double sessions begin in earnest. Seidenberg played all 82 games last season while returning from major surgery on his right knee, and has been a steady participant in the captain’s practices over the last few weeks. With or without Seidenberg, the Bruins will take the ice for double session practices on Friday, and will hold open practices to the public at TD Garden on both Saturday and Sunday beginning with the 10 a.m. start of the first session.
