Tragedy struck at the Churchhill Downs racetrack just days before the Kentucky Derby. A three-year-old colt threw his jockey and took off out of control down the track, crashing into another horse and jockey and sending all tumbling to the ground. The horse that was crashed into was a two-year-old philly that was injured so badly she had to be euthanized.
