The Toronto Maple Leafs received some good news as All-Star defenceman Tomas Kaberle rode a stationary bike Friday, the first physical exertion Kabele has been able to do since being leveled by Devils enforcer Cam Janssen.
Head Coach Paul Maurice says Kaberle felt good afterwards and if he experiences no headaches or other setback, could return to the ice for practice in a week’s time.
