Big Brown's racing career over

W YORK - Kentucky Derby and Preakness winner Big Brown's racing career is over after injuring his right front foot during a workout at Aqueduct on Monday.

Trainer Rick Dutrow said the 3-year-old colt, who was preparing for the Breeders' Cup Classic on Oct. 25, appeared to kick himself while working on the turf course at Aqueduct with stablemate Kip Deville. Big Brown was able to complete the six-furlong work when Dutrow noticed blood coming out of the foot. "It looks like he grabbed himself in a bad spot," Dutrow said. Though the extent of the injury is unknown, Michael Iavarone of IEAH Stables, said the horse who captivated the racing world during his Triple Crown will not race again.
