The Bruins took care of their biggest player set to become a unrestricted free agent Tuesday morning, inking second-line winger Rich Peverley to a three-year contract extension.

Peverley was acquired on Feb. 18 last season when the Bruins sent Mark Stuart and Blake Wheeler to Atlanta for the speedy forward and defenseman Boris Valabik.

Peverley leads the Bruins with two goals this season, both of which were scored in Saturday’s win over the Lightning. His signing leaves Chris Kelly, Gregory Campbell, Shawn Thornton, Daniel Paille, Joe Corvo and Johnny Boychuk as the remaining players set to become unrestricted free agents at season’s end.
