Boston Bruins captain Brad Marchand is officially out "week-to-week" with an upper body injury, interim coach Joe Sacco announced Tuesday.
Marchand missed Sunday's 1-0 loss to the Minnesota Wild one day after being injured on a hit by Pittsburgh Penguins defenseman P.O Joseph, with Marchand's head hitting the boards. After receiving attention from a trainer for several minutes, Marchand was helped from the ice.
Sacco would not specify if it was a head injury for Marchand, who has a history of concussions. The 36-year-old winger has 47 points in 61 games this season, second on the Bruins.
