General manager Don Sweeney made the announcement Saturday, adding the deal through the 2019-20 season includes an additional $1.75 million in performance bonuses.

Chara is in his 13th season with Boston and 21st in the NHL. He is the second-oldest active NHL player, behind Pittsburgh's Matt Cullen.
