Andrew Alberts (concussion) is still getting headaches on a daily basis and his NHL career may be over. Alberts suffered the concussion on December 29 when he was hit high by the Flames Brian McGrattan and while he was headache-free for a couple of days in April, the headaches have returned. Alberts becomes an unrestricted free agent on July 1 and at age 33, his career could be over.
