Bruins General Manager Peter Chiarelli said Friday that Peverley suffered a third-degree sprain of the medial collateral ligament in his right knee during the Bruins' game against the Montreal Canadiens on Wednesday.
Peverley is second on the Bruins with 29 assists, and he also has nine goals and 38 points in 49 games.
The team had called up Josh Hennessey from AHL Providence on Thursday, and the native of Brockton, Mass., will make his Bruins debut tonight in Winnipeg.

I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
