Zdeno Chara suffered a significant injury during Monday night's loss to the St. Louis Blues in Game 4 of the Stanley Cup Final.

The Boston Bruins captain broke his jaw, a source familiar with the situation told The Athletic's Jeremy Rutherford on Tuesday.

Chara left the game after Blues forward Brayden Schenn took a shot that deflected off the defenseman's stick and up into his face in the second period.

The 42-year-old blue-liner returned to the bench for the third period, but he didn't play another shift.
