Kentucky Derby doping scandal

Dancer's Image, in a thrilling last-minute finish, wins the Kentucky Derby, but is disqualified three days later after testing positive for a painkilling drug. The colt is the only Derby winner in history to have its crown taken away. Sports Illustrated calls the scandal the "sporting story of the year."
