Boston Bruins goaltender Tuukka Rask had to be helped off the ice after rookie forward Anders Bjork collided with him in front of the net during practice Wednesday.
Rask did not return and there was no immediate word on his condition. The Bruins play the Vancouver Canucks at TD Garden on Thursday (7 p.m. ET; SN360, TVA Sports, NESN, NHL.TV).
"He left early obviously," coach Bruce Cassidy told the Bruins website. "We had a line-rush drill where there was some contact around the net. He'll get evaluated. I've got nothing right now; hopefully he's fine. Until he gets checked out, I don't know. That's where it's at right now."

Bjork appeared to be knocked off balance before the collision. Teammates immediately rushed to Rask's assistance and he was helped off the ice after a couple of minutes.
"It was incidental contact on a hard drill," Cassidy said. "We're trying to build in more net action and net drive. I guess that's the spillover from it sometimes."
If Rask is unable to play against the Canucks, backup Anton Khudobin likely would get his second start of the season, with Zane McIntyre recalled from Providence of the American Hockey League to be his backup. Khudobin made 29 saves in a 6-2 win at the Arizona Coyotes on Saturday.
"We liked the way Anton played last year at the end of the year, we liked he's camp, we liked his first game," Cassidy said.
Rask, 30, is 1-3-0 with a 3.30 goals-against average and.882 save percentage in four games this season.
