Boston Bruins defenseman Torey Krug suffered a left ankle injury and is set to be re-evaluated after three weeks of wearing a walking boot, general manager Don Sweeney announced.

Krug fractured the same ankle during the club's second-round series versus the Tampa Bay Lightning last season, but his current ailment is unrelated, Sweeney said.

The 27-year-old recorded 59 points while averaging over 20 minutes of ice time per game last season.

The Bruins kick off their season Wednesday in Washington against the Capitals.
