Dennis Seidenberg played only 37 seconds in Game 7 after suffering leg injury.
The rearguard limped off following a leg-on-leg collision with the Leafs' Matt Frattin, so the team had to play most of the game with only five defensemen. It is unclear how serious the injury is; the Bruins expect to learn more Tuesday. "He wanted to (continue), but when he couldn't, it was better to take (him) out than to make it worse," Bruins coach Claude Julien said. "It wouldn't have helped us, plus, it would have made his injury probably even worse."
