“Sáez is being evaluated by University of Kentucky HealthCare Medical Services and in stable condition,” a Keeneland spokesperson said in a written statement that also was posted to social media shortly after the mishap. “He will be off his mounts for the remainder of the day.”

“He was moving,” said Irad Ortiz Jr., who was among the riders who ran onto the track after the race to check on Sáez. “He looked alert.”
