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 don't think it's really truly going to sink in until we drop the puck, to be honest. I know there's going to be a lot of smoke and mirrors with the media attention and all that. We came [Monday] and it was sort of a light day to get things organized. We just want to focus in on the business aspect, the game itself. That's what we're preparing to do. Get these next couple of days out of the way and it's game on.
