LOUISVILLE, Ky. – Thunder Snow bucked wildly just after the start of the Kentucky Derby and did not finish the race, but all signs point to the colt being uninjured. Thunder Snow was away slowly and almost immediately dropped to the tail of the field, and when jockey Christophe Soumillon threw the reins at him to try to urge his mount into the race, Thunder Snow bucked several times and quickly was pulled up. Thunder Snow was picked up by an outrider and taken to the paddock, where he was examined by a regulatory veterinarian. The colt appeared to be uninjured and walked back to the stakes barn on the backstretch, where he has been housed since arriving here from England on Sunday. Back at the barn, trainer Saeed bin Suroor already had departed, but stable employees confirmed that Thunder Snow had come back showing no signs of injury. The colt, who won the UAE Derby on a muddy track to qualify for the Kentucky Derby, was scheduled to fly home to England on Thursday.
