WILMINGTON, Mass. — Bruins general manager Peter Chiarelli clarified that David Krejci suffered a moderate concussion Saturday night against St. Louis.

The GM said that instead of numbers, doctors now use mild, moderate and severe to grade concussions. Krejci never lost consciousness and has felt better both yesterday and today.

The initial symptoms were headache and slight amnesia. As far as Chiarelli knows, there were no additional injuries (i.e. neck, nose) suffered as a result of the hit with T.J. Oshie and the subsequent collision between Krejci’s head and the boards.

“He’s be re-evaluated [Tuesday],” said Chiarelli. “As far as time frame goes, I don’t know. All indications are, one, it being a moderate concussion, two, the ways he’s feeling in the first two or three days following a concussion — those most critical in gauging a prognosis — he’s been good in that time period.”

Chiraelli also said that Krejci might have his next baseline test later in the week.

“It was a coincidental hit, an incidental hit,” said Chiarelli. “David put himself in that position, Oshie was there, David wanted to hit him at that point. It was just one of those things. I have no problem with the hit.”
