Boston Bruins goaltender Tuukka Rask has been diagnosed with a concussion and will receive treatment as outlined by the NHL's protocols, the team announced Thursday.

Rask suffered the concussion when he was bumped by teammate Anders Bjork during practice on Wednesday, and no timetable has been set for his return due to the nature of the injury.

The Bruins already announced Anton Khudobin will start Thursday against Vancouver, and Zane McIntyre has been recalled from AHL Providence to serve as backup.

Losing Rask after waiving Malcolm Subban earlier this season will put Boston's goaltending depth to the test for the immediate future.

Rask posted a record of 1-3-0 with a .882 save percentage prior to the injury, while Khudobin stopped 38 of 40 shots for a win in his lone appearance this season.
