** ADVANCE FOR WEEKEND EDITIONS, JAN. 17-18 ** FILE ** In this Jan. 6, 2009 file photo, Philadelphia Flyers' Simon Gagne (12) moves the puck during the second period of an NHL hockey game against the Washington Capitals in Washington. Each time Simon Gagne tried to return from a brutal concussion, the symptoms were quick to surface. Gagne is back for the Flyers and is feeling fine. But if he had his way, the NHL would ban shoulder-to-head hits _ the one that resulted in his head injury. (AP Photo/Luis M. Alvarez, File)
