John Velazquez

Up an Octave, ridden by John Velazquez, collapses and rolls onto Velazquez shortly after crossing the finish line to win the Forerunner Stakes at Keeneland in Lexington, Ky., Thursday, April 20, 2006. Velazquez was carried on a stretcher to a first aid facility at the track, then taken by ambulance to University of Kentucky Hospital for testing and X-rays, where he was stable Thursday night. Up an Octave fractured a leg after the race and had to be euthanized on the track, Keeneland spokeswoman Amy Gregory said. (AP Photo/Charles Bauer)
