The 2026 Kentucky Derby got off to a chaotic start on Saturday evening, as race officials were forced to delay the "Run for the Roses" after a dramatic pre-race incident involving replacement horse Great White.

Just minutes before the starting gates were set to open, the high-strung thoroughbred became visibly agitated, rolling on the track and violently throwing its jockey to the ground. The startling moment, captured on video and quickly shared across social media, sent shockwaves through the Churchill Downs crowd.

Track veterinarians and officials immediately scratched Great White from the race, prioritizing the safety of both horse and rider. The commotion also forced a complete reset, with all 19 remaining horses having to be removed from the starting gate and reloaded—a rare and tense procedure that added nearly 20 minutes to the delay.

For fans and bettors alike, the scene was a stark reminder of the unpredictable nature of horse racing, where even the best-laid plans can unravel in an instant. The Derby, known for its pageantry and tradition, saw an unusual hush fall over the grandstands as crews worked to calm the remaining field.

Great White, who had been entered as a last-minute replacement, was reported to be uninjured after the incident. The jockey was also evaluated and was walking under his own power.

This is a developing story. We will provide updates as more information becomes available from Churchill Downs officials and the Kentucky Derby media team.
