An Australian Ice Hockey League game (yes they plan hockey in Australia) had a scary moment when a linesman was caught in the action and got an accidental elbow to the head, suffering a concussion.
Broadcaster Stephen White, calling the game for Fox Sports Australia, had his gear with him, as he was due to play in a minor-league game afterwards, went from the booth to the blue line and replaced the injured official. Everything begins at 0:55.
