Bruins goalie Tuukka Rask out indefinitely due to concussion

Boston Bruins starting goalie Tuukka Rask has been diagnosed with a concussion and is out indefinitely, the team said.

Rask was injured in a collision with rookie forward Anders Bjork during practice Wednesday. He needed assistance to leave the ice.

Anton Khudobin started in goal against the Canucks on Thursday. Zane McIntyre was brought up from Providence to serve as Khudobin's backup.

Center Patrice Bergeron made his season debut Thursday after being sidelined by a lower-body injury. Coach Bruce Cassidy had called Bergeron a game-time decision after Bergeron wore a non-contact jersey during the morning skate.
