The Boston Bruins say forward Shawn Thornton will miss 7-10 days with a concussion.
Thornton was injured in the first period of Thursday night’s game against Buffalo when he fought with Sabres forward John Scott. He did not return.
Thornton has one goal and 25 penalty minutes this season.
The Bruins recalled forward Jamie Tardiff from the AHL on Friday. Tardiff leads the Providence Bruins in scoring with 21 goals and nine assists in 39 games.
Thomas Vanek had three goals and two assists, setting up the tiebreaking score with 13:06 left in the third period on Thursday night to lead the Buffalo Sabres to a 7-4 victory over the Boston Bruins.
Vanek opened the scoring 98 seconds into the game, then had a goal and an assist to tie it after Boston took a 3-1 lead in the second. The Bruins went up 4-3 in the third before Alexander Sulzer tied it on a wrister from the faceoff circle, and then Vanek helped give Buffalo the lead when he kept the puck in the zone, faked a shot and slid it over to Cody Hodgson for the game-winner.
Ryan Miller made 38 saves for Buffalo, which ended a four-game winless streak.
Tuukka Rask stopped 25 shots for the Bruins.
