03:51 PM ET 03.25 | The Philadelphia Flyers announced on Monday afternoon that forward Danny Briere would be out indefinitely after sustaining a concussion. The injury occurred during the team???s practice on Saturday morning when Briere collided with the boards. He was ruled out for Sunday night???s game against the Pittsburgh Penguins due to an upper-body injury. He did not travel with the team. This marks Briere???s second concussions in as many seasons. With the 35-year-old???s production down this season, many have speculated that the Flyers would look to move Briere. Of course, that would have been a difficult venture given his no-movement clause and now nearly impossible with this injury.
