Joanne Vaughan, who competes for the country of Georgia, was injured in a fall at the Adequan Global Dressage Festival in Wellington, Florida, on Feb. 28.

Vaughan was warming up Forbes, a 10-year-old Hanoverian gelding (Fidertanz—Rhonda, Rohdiamant), for the CDI3* Intermediaire I freestyle when a sprinkler went off and spooked him.

Vaughan, 59, sustained a broken collarbone, several fractured ribs and a bruised and collapsed lung. She was transported to Palms West Hospital in nearby Loxahatchee.

“I’ve received so many nice messages from all over the world,” she said. “Because the boards were right in front—it was one of those very fast things. We were just doing our usual warm-up—I still had 25 minutes—and the sprinklers went on. He went to run forward, saw the boards, and then jumped the other direction and swerved. I was a little bit launched, almost like going backwards. He’s not a spooky horse. I’ve been riding him since he was 3 and never had a problem with him. It’s the first time I’ve come off him. It was one of those freak accidents.”
