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.

You don't see many. The [Drew] Doughtys, the [P.K.] Subbans, those are guys that create offense from the back and then on top of that ability, the size that he has. In the West you play against some pretty big players, and being able to clear the crease and contain the [Ryan] Getzlafs and the [Corey] Perrys and [Anze] Kopitars and players like that, we're excited about him going back there.
