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.

The groove of being behind a bench is going to be interesting at first, but thank God we have a few exhibition games to get rid of those cobwebs. Overall the excitement of it all and the freshness and coming back refreshed, all those things are going to be assets. If [the players] come ready to give their best effort in practice and games, good things are going to happen. I'm always looking for results. It's not always on the scoreboard. It's winning and building something.
