SACRAMENTO (AP) — Former Kentucky Derby-winning jockey Patrick Valenzuela has lost his bid to ride in California for now.

The California Horse Racing Board has accepted a hearing officer’s recommendation to deny Valenzuela a jockey’s license, although he may re-apply in one year. At that time, he would have to present evidence of rehabilitation, including results of alcohol and drug testing performed on no less than once a week.

Valenzuela’s license to exercise horses in California remains in good standing.

The CHRB met in executive session last week to consider hearing officer Patrick Kane’s decision in which he wrote that since 2000, Valenzuela has had what Kane considers 15 major rule violations and-or convictions. Kane said that six months free of violations failed to demonstrate that the jockey was adequately rehabilitated.

Kane encouraged Valenzuela to reapply in the future if he continues to maintain a clean record and regularly attends substance abuse meetings.

The 53-year-old jockey has over 4,000 victories in a career marred by substance abuse and no-shows.

He won the 1989 Kentucky Derby and Preakness aboard Sunday Silence, and has six career Breeders’ Cup wins.
