(The Sports Xchange) - Boston Bruins goaltender Tuukka Rask suffered a concussion in a practice collision with rookie teammate Ander Bjork on Wednesday and has entered the NHL's concussion protocol.
The club issued a statement Thursday afternoon, prior to Rask missing the game against the Vancouver Canucks.
Earlier, it was announced Rask would not start and that the Bruins had recalled Zane McIntyre to back up Anton Khudobin.
Rask is just 1-3-0 on the young season, had lost his last three starts and has an .882 save percentage in his four starts.
Boston also recalled goaltender Zane McIntyre from Providence of the American Hockey League on an emergency basis. With Rask sidelined, backup Anton Khudobin was scheduled to start Thursday night against the Canucks.

Bruins forward David Backes, who has yet to play this season while dealing with diverticulitis, was activated off injured reserve and is eligible to play against visiting Vancouver.

Boston also placed forward Ryan Spooner on injured reserve. Spooner is expected to be sidelined for four to six weeks after suffering a right groin adductor tear. He was injured in Boston's 3-1 loss at expansion Vegas on Sunday.

Los Angeles Kings center Jeff Carter underwent surgery to repair a cut on his left leg sustained in Wednesday night's game.
Kings vice president and general manager Rob Blake said in a statement that Carter will be out indefinitely. TSN reported that the procedure on Carter was to repair a damaged ankle tendon, adding a best-case scenario for recovery is six to eight weeks.
In addition, the Kings gave a two-year contract extension to defenseman Derek Forbort and signed forward Brooks Laich to a one-year deal.
The 32-year-old Carter has three assists in the first six games this season, but he pumped in 32 goals in 2016-17 -- his highest output since scoring 36 times for the Philadelphia Flyers in 2010-11.
Forbort, a first-round draft pick (No. 15 overall) of Los Angeles in 2010, has a pair of assists in six games this season. His deal has an average annual value of $2.525 million.
Laich, 34, signed a one-year, two-way contract worth $650,000 if he sticks with Los Angeles.
