The Puma scratches from Kentucky Derby field after leg swelling setback

The Puma was out of the Kentucky Derby about 12 hours before post time, a swollen pastern in his left front leg ending the run of one of the race’s most recognizable Florida Derby runners and cutting the field from 20 to 19. The scratch landed with immediate force at Churchill Downs because The Puma had been 8-1 in early wagering, the fifth choice on the board, and had been expected to factor into the early pace and positioning discussion after a strong prep season.

The colt’s issue was tied to a skin infection, and Gustavo Delgado Jr. said The Puma was lame when jogged and would need antibiotics. Delgado Jr. also said it was unlikely the horse would be ready in time for the Preakness Stakes, turning a Derby-week contender into a horse whose short-term schedule suddenly disappeared. Javier Castellano had been named to ride.

For bettors and handicappers, the scratch changed more than the size of the field. The Puma had earned his way into the Derby conversation with a victory in the Grade 3 Tampa Bay Derby on March 7, stopping the clock in 1:43.23 after rallying from last in a nine-horse field, then following it with a nose defeat in the Grade 1 Florida Derby on March 28. That runner-up finish gave him 56 Kentucky Derby qualifying points and made him a serious presence in a race where form from Florida had recently mattered. Mage won the Derby in 2023 after finishing second in the Florida Derby, and Sovereignty repeated that path in 2025.

The withdrawal also altered the pace map. The Puma had been one of the better-known off-the-pace types in the field, so his exit removed a colt with proven graded-stakes form and another possible piece in the scramble for position into the first turn. Under Derby rules, every horse drawn outside him moved in one spot, a small administrative shift that still rippled through the post positions with the race set as event 12 at 6:57 p.m. ET on May 2, 2026.

The Puma’s backstory had added intrigue all week. Trained by Gustavo Delgado, who was making his fourth Kentucky Derby start after Majesto, Bodexpress and the injured Caracaro, the colt carried ownership that included OGMA Investments, JR Ranch, High Step Racing, Michael Iavarone, Jules Iavarone and Bruce Zoldan. Bred by Hidden Brook Farm and Brian Kahn and sold for $150,000 at OBS April, he had looked like a legitimate contender. Instead, the leg swelling brought another sharp reminder of how fragile Derby plans can be.
