Assistant trainer Yvonne Azeff, who was injured Saturday after being thrown and pinned beneath the stable pony, was still unconscious at Memorial Regional Hospital in Hollywood, Fla. as of Monday morning, a spokesperson at trainer John Ward's barn said. All tests have proven negative and all her vital signs are good. "She's getting better, but very slowly," the spokesperson said.A hospital spokesperson in the intensive care unit said Memorial Regional does not issue patient updates. Due to the number of calls that had been received, Azeff's family requested that people concerned about her condition refrain from contacting the hospital.Azeff, who is an assistant to Ward and had a major role in developing Kentucky Derby (gr. I) winner Monarchos, was on the stable pony during training hours at Gulfstream Park. The pony lost his composure when the horse he was accompanying from the track became unruly. The pony then ran off, ducked from a barn wall, and eventually bounced off a fence, losing his balance. He unseated Azeff, then fell on top of her, pinning her beneath him. He quickly got to his feet, but Azeff remained on the ground, unconscious.Azeff, 41, previously worked as an assistant to top trainers such as D. Wayne Lukas, Pat Byrne, and Randy Bradshaw.
