Danon Bourbon (Maxfield), who finished fifth in this year's GI Kentucky Derby behind Golden Tempo (Curlin), has been found to have a fractured knee upon his return to Japan, trainer Ikezoe announced Wednesday.“The fracture in his knee was discovered after the Kentucky Derby,” Ikezoe said. “After returning to Japan, he had X-rays taken for confirmation and has completed quarantine at the Japan Racing School, so he will now undergo surgery to remove the bone fragments at the Shadai Clinic in Hokkaido in preparation for his return. The timing of his return is undecided as it depends on the results of the surgery and the rehabilitation that follows, but I think he will focus on resting for the rest of the year.”The $450,000 Keeneland September grad was previously undefeated in three starts in Japan prior to his run in the Derby. 【残念なお知らせです】ケンタッキーダービー5着のダノンバーボンが骨折池添師「年内は休養に専念すると思います」#ダノンバーボンhttps://t.co/7mBUxWBZcP— netkeiba (@netkeiba) May 13, 2026The post Kentucky Derby Runner Danon Bourbon Sidelined With Knee Fracture appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
