The Bruins reported today that Adam McQuaid had arthoscopic surgery on his ankle, after he had an issue with a quad, and a bunch of other things. He hasn't played since January 19th of this year. He assisted on the Bruins' first goal, and then had his last shift a bit before the Chicago 2-2 goal. He hasn't played since.
McQuaid's minutes have been replaced serviceably by Kevan Miller. McQuaid is signed through next year.
