Late in his first shift of the game, Seidenberg was injured during a scramble in front of the net, although it wasn't immediately apparent that he was hurt on the play. Boston iced the puck shortly after the hit, forcing Seidenberg to stay on the ice. He left after the next faceoff and did not return.
Coach Claude Julien said after the 2-1 victory that it was "obviously a lower body injury where he couldn't come back" and that Seidenberg would be evaluated after the team returned to Boston.
In 20 games this season, Seidenberg has six assists and a plus-10 rating. He has missed five games in the previous three seasons.
