Ex-NHL player Johnson dies after on-ice accident

The Nottingham Panthers, who play in England's Elite Ice Hockey League (EIHL), announced Sunday that the organization is "heartbroken at the news of Adam's passing."

Officials stopped the Panthers' game Saturday against the Sheffield Steelers after Johnson was involved in a collision on the ice during the second period. Johnson received emergency treatment on the ice, and players eventually returned to the locker room after he was taken to Sheffield's Northern General Hospital.

Nearly 8,000 fans at Sheffield's Utilita Arena were asked to leave the building because of what the Panthers announced as a "major medical emergency."
