Nathan Horton (concussion) isn't working out. "He's at the stage he was earlier on," Bruins coach Claude Julien said. "We've got to be patient with that. As I've said before to my trainers and doctors, as long as symptoms are there, you're not going to hear a peep from me. I respect the seriousness of it all. You've got to give the guy the best opportunity possible to get himself better." It's entirely possible that Horton won't return before the end of the regular season.
