It was a rough day at the office for the Bruins on Sunday.

Not only did they end up losing 4-2 to the Capitals after allowing three straight goals, but the Bruins also lost another key member of the lineup.

Matthew Grzelcyk left the game with what Boston called an upper-body injury.

While the play that led to him being hurt seemed meaningless, it is a cause for concern for the defenseman.

Grzelcyk, who already has a history of separated shoulders, appeared to immediately grab his shoulder after the play.

Let's hope that he can avoid any serious injury with the playoffs just a few weeks away and Boston already down the services of Hampus Lindholm.
