Concussion updates. Both Keith Primeau and Jeremy Roenick have reported some improvement in their recoveries from concussions. Primeau was at the rink briefly yesterday and reported feeling better, but is still not able to exercise. Hitchcock remains optimistic he could be three weeks away from rejoining the club. Primeau was not available to reporters. Roenick said yesterday from his off-season home in Phoenix that he had back-to-back "good days" and would like to return to the Philadelphia area tomorrow. He is trying to advance his medical timetable and schedule his appointment with neurologist Karen Johnston this week instead of next week. "No headaches for two days," Roenick said. "That's a good sign."
