Carl Soderberg may have suffered a concussion Friday night when his head bounced off the turnbuckle on a hit from Ottawa's Erik Karlsson. Coach Claude Julien didn't specify an injury for Soderberg, who appeared to be woozy after the check. The Boston bench boss told the media on Saturday morning that Soderberg didn't make the trip to Ottawa for Saturday's game. Consider him day-to-day for now.
