(FILES)Jockey Kent J. Desormeaux(L) riding "Big Brown" crosses the finish line for First Place at the 133rd Preakness Stakes May 17, 2008, at Pimlico Race Track in Baltimore, Maryland. Triple Crown contender Big Brown has missed two days of training with a left hoof injury, trainer Rick Dutrow jnr said on May 25, 2008. The colt, trying to become the first in 30 years to sweep US flat racing's Triple Crown races, has a quarter crack - a vertical crack in the hoof wall - on the inside of his left front hoof. Dutrow admitted he was somewhat concerned by the injury. But the trainer also said it would not prevent Big Brown, winner of the Kentucky Derby and Preakness Stakes, from running in the Belmont Stakes on June 7. AFP Photo/Paul J. Richards
