Trainer Doug O’Neill said that I’ll Have Another, the Santa Anita Derby winner, had shock-wave therapy on his back.
“The legal, licensed machinery is great therapy for backs,” O’Neill said. “We’ve done it with him a few times in the past.”
The treatment, though legal and regulated in California, does require a horse to be placed on the state racing board’s veterinarian list for 10 days, during which time he cannot race. According to Dr. Rick Arthur, the equine medical director for the California racing board, I’ll Have Another was placed on the list April 21 and comes off the list May 1, four days before the Derby. As of Wednesday, there were 28 horses on the racing board vet’s list for shock-wave therapy, including such well-known runners as Midnight Interlude and Richard’s Kid.
