Post-Derby Setback Confirmed By Danon Bourbon Connections In Japan

Promising Japanese racehorse Danon Bourbon will miss the rest of the 2026 season after a knee injury was discovered when he returned to Japan following the Kentucky Derby.

Thoroughbred Daily News reported trainer Manabu Ikezoe saying the issue was identified after the colt came home and underwent X-rays, with surgery now planned at the Shadai Clinic in Hokkaido.

The Paulick Report also reported that Danon Bourbon, who has banked $372,762 in prize money, will be out for the rest of the year, citing Japanese racing liaison Kate Hunter.

“He will undergo surgery at the Shadai Clinic and take the rest of the year off to heal”

With the Paulick report describing the problem a knee chip, while Thoroughbred Daily News reported it as a fracture, but both reports agree that surgery is planned and that no return is expected in 2026.

The only horse on the pace to stay there till the end. Poor Danon Bourbon came out of the Derby with a chipped knee. He will undergo surgery at the Shadai Clinic and take the rest of the year off to heal. I can’t wait to see this beast again. Wishing him a speedy recovery. https://t.co/GlFug7fSww pic.twitter.com/SqbKFDSRYX
