Boston Bruins captain Brad Marchand did not play in Sunday's 1-0 loss to the Minnesota Wild, one day after leaving in the first period against Pittsburgh because of an upper-body injury.
Marchand departed after a hit by Penguins defenseman P.O Joseph at 5:56. Joseph drove Marchand into the corner, and the side of his head struck the boards. No penalty was called, but Mason Lohrei scored at 6:33 to give the Bruins a 2-0 lead.
A trainer attended to Marchand for several minutes before he was helped from the ice.
Later in the period, Joseph took a hit in the corner from Bruins forward Mark Kastelic and left because of an upper-body injury.
On Sunday, before the loss, Bruins interim coach Joe Sacco addressed the situation with few specifics.
"There's really nothing to report yet. He's out today," Sacco said. "We'll know more when he gets evaluated when we get back to Boston. It's an upper-body injury right now."
Marchand has 21 goals and 26 assists in 61 games in his 16th season with the Bruins. Last month, he helped lead Team Canada to a win in the 4 Nations Face-Off.
