Omaha Beach has what appears to be the beginning of a fracture in his right hind leg and will be scratched from the $3 million Pegasus World Cup on Saturday at Gulfstream Park, trainer Richard Mandella said Thursday afternoon.

"He went out for a gallop this morning, cooled out great, but we noticed something later," Mandella said. "We X-rayed his right-hind ankle. It's questionable what's there, but it looks like it might be the beginning of a cannon-bone fracture. We can't take a chance."

Mandella said the X-rays were sent to noted veterinarian Dr. Larry Bramlage, who evaluated the images.

The Pegasus was scheduled to be the final start for Omaha Beach before going to stud next month at Spendthrift Farm. His star-crossed career included having to be scratched from the Kentucky Derby owing to an entrapped epiglottis days before the race. He raced 10 times, and won three Grade 1 races.
