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.

It's a tribute to him, and everything he's done and deserved is coming to fruition tonight with his jersey in the rafters. He's going to be a first-ballot Hall of Famer. And I said today, if he's not, take my stuff out. If he doesn't deserve to be in there first ballot, no one does. Except for (Wayne) Gretzky, I guess.
