Poitras sustained an undisclosed injury against the Golden Knights on Monday, and there was no update on his status after the game, Jack Studley of Boston Hockey Now reports.
Poitras was elbowed by Braeden Bowman during this game, which resulted in a major penalty and game misconduct for the Vegas forward. Head coach Marco Sturm should have information to relay on Poitras' status prior to the Bruins' next game, which is Thursday in Pittsburgh.
