Bruins' David Krejci has concussion

BOSTON -- Boston Bruins forward David Krejci suffered a concussion during a collision in overtime of the team's 2-1 shootout loss to the St. Louis Blues Saturday night at TD Garden and will be out for at least a week, the Bruins said Sunday.

The Bruins said Krejci will continue to be evaluated by the club's medical team.

A team source had said after the game that Krejci suffered a mild concussion, with the source adding, "but it's not bad." Krejci also suffered a minor facial laceration.

With the game knotted at 1-1 with 4:16 remaining in overtime, Krejci and the Blues' T.J. Oshie collided in front of the penalty boxes with Krejci taking the worst of the hit. His head smashed against the boards. He lay on the ice and was attended to by team trainer Don DelNegro. Krejci was able to skate off the ice with some assistance from a couple of his teammates.

Oshie said after game he thought the hit was clean.

"It was two guys going at the puck," he said. "I tried to get low and get a good center of gravity. It looked like he was coming to hit me as well. It was a hard battle tonight. It was a physical game. I certainly hope that he's OK and he'll be right back."

Krejci suffered a season-ending wrist injury during Game 3 of the Eastern Conference semifinals against the Philadelphia Flyers last spring, and needed immediate surgery to repair the damage. He arrived at training camp this season healthy.
