Tuukka Rask will be out at least two games for the Boston Bruins because of an upper-body injury.

The goalie will not play when the Bruins host the Buffalo Sabres on Saturday (1 p.m. ET; SN1, NESN, MSG-B, NHL.TV) nor Sunday against the New Jersey Devils.

Rask played one period for the Boston Bruins against the New York Islanders on Thursday before leaving the game.
