Daniel Sedin out for Canucks

CHICAGO -- Canucks leading scorer Daniel Sedin left Wednesday's 2-1 overtime loss to the Chicago Blackhawks midway through the second period with an apparent injury and did not return at the start of the third.

Sedin might have been hurt when he was elbowed in the head by Chicago defenseman Duncan Keith late in the first period.

The Blackhawks and Canucks have squared off in emotional postseason series each of the past three years. And the feelings resurfaced Wednesday night.

"Everybody saw the head shot there, so [Sedin will be] re-evaluated tomorrow and I'll know more from there," Canucks coach Alain Vigneault said.

As Sedin turned away from the boards at center ice, Keith appeared to hit him with an elbow, knocking him to the ice immediately. Sedin took a shift on the ensuing two-minute power play, then left for the night.

"Deliberate, principal point of contact, everything you're trying to take out of the game," Vigneault said.

Keith, the Blackhawks' top defenseman and the 2010 Norris Trophy winner, received only a minor penalty on the play.

"I expected a major, and I got a minor, so we'll let the league deal with it," Vigneault added. "You saw the hit, you didn't see a puck near the hit, you guys make the judgment call on that, and the league will do what they have to do."

"I'm not trying to hurt anybody," Keith said "I hope he's OK. He's one of their best players. He needs to be on the ice."

Keith said several times he needed to see a replay of the hit before he could make a final assessment on it.

"It's a fast game," he said. "I'm not trying to hurt anyone. I haven't seen the replay so I really can't comment on it."

Sedin has 30 goals this season, most on the Northwest Division-leading Canucks. The score was tied at 1.
