Jockey Tim Doocy sustained fractures to his ankle, knee, and hand during a morning training accident at Oaklawn Park in Hot Springs, Ark., on Monday. He was scheduled to undergo surgery on Monday afternoon. Oaklawn, which is open for training, begins its meet Jan. 15. Doocy, 54, was injured when a horse he was pulling up from a work collided with a pony chasing a loose horse. He was taken to St. Joseph's Mercy Health Center in Hot Springs. "The [horse] was galloping out strong" Doocy said in a release issued by Oaklawn. "And I just didn't see [the pony] until too late. We hit head on." Both horses, a 2-year-old colt named The ATM, and the pony, who was ridden by Chisum Ewing, were euthanized. Ewing sustained no serious injuries in the accident. Doocy, who was sidelined over the summer with a broken arm, returned to race riding in October at Remington Park. He is a career winner of more than 5,000 races.
