LEXINGTON, Kentucky (AP) " Jockey Robby Albarado will miss the Kentucky Derby after breaking his left ankle in a riding accident at Keeneland.
Albarado was scheduled to ride J Boys Echo for trainer Dale Romans in the Derby on May 6.
He got hurt after his horse stumbled at the start of a race Sunday at Keeneland, unseating Albarado on the turf. He was taken to a hospital for X-rays and further evaluation.
Agent Rob Ebanks says Albarado will be sidelined for some time.
Romans tweeted Sunday: "A miracle it wasn't worse. Wishing best to Robby Albarado, his health is 1st."
The trainer says he will discuss replacing Albarado with the horse's ownership.
J Boys Echo won the Gotham Stakes and finished fourth in the Blue Grass, his last start before the Derby.
