Bolt fails to make grade Down Under

SYDNEY - Sprint king Usain Bolt's attempt to become a professional soccer player with Australia's Central Coast Mariners collapsed on Friday as his trial period was terminated after contract talks failed.

The eight-time Olympic champion had been trying out with the A-League side for an indefinite period since arriving in August, hoping to fulfill a childhood dream to become a soccer player.

The 32-year-old superstar's quest garnered worldwide attention, which intensified when he scored two goals in a preseason friendly.
