Runhappy sidelined with bruised cannon bone
USA: Runhappy will spend the next two months rehabilitating after being diagnosed with a bone bruise on his off fore (front right) cannon bone.
Owned by Jim ‘Mattress Mack' McIngvale, Runhappy is unbeaten in his last six starts, including the Grade 1 King's Bishop Stakes, Grade 1 Malibu Stakes and Breeders' Cup Sprint.
The four-year-old had returned to strong exercise last month after a break, but a problem was diagnosed after trainer Laura Wohlers recognised Runhappy was not stretching out properly.
"He had been reluctant to gallop," Wohlers told bloodhorse.com. "He'd jog all day long, and he had no problem when he galloped the wrong way. The fact he was reluctant to gallop the other way suggested something was wrong. Now we know why. We'll give him 60 days and see where we are.
"If you catch it early enough, then the injury will resolve itself. If you keep training, you can develop a chip or condylar fracture. It leads to bigger problems."
Connections remain confident Runhappy will be able to defend his Breeders' Cup title at Santa Anita on November 5. The inaugural $12 million Pegasus World Cup at Gulfstream Park in January is also reportedly a target.
