The Kentucky Derby faced a last-minute scare on Saturday when Great White was removed from the competition just moments before the race began at Churchill Downs.
What happened to Great White? A scary video shows the horse bucking and throwing his jockey before flipping onto his back near the starting gate.
Medical personnel and track veterinarians quickly evaluated both the horse and the rider, who avoided serious injury.
Despite the jockey's safety, officials decided to err on the side of caution and scratch Great White from the competition.
The scratch reduced the field from 19 horses to 18 just before post time.
Golden Tempo stormed to victory at the 152nd running of the Kentucky Derby, making Cherie DeVaux the first woman to train the winner in the "Run for the Roses."
DeVaux expressed her pride in being a representative of women everywhere, saying, 'We can do anything we set our minds to.'
