The Boston Bruins are awaiting word on the severity of Brad Marchand's injury, which would affect either the team on the ice or the front office's plan for the NHL trade deadline.

Boston Bruins captain Brad Marchand is unlikely to return to Saturday's game against the Pittsburgh Penguins after suffering an upper-body injury in the first period.

In their 3-2 victory over the Penguins that went down to the final white-knuckle seconds – just their second road win since the Christmas break – captain Brad Marchand was lost to a scary injury in the first period, making it the third straight game they had to finish down a man.
