A closeup of Big Brown is seen just after the start of the 140th Belmont Stakes horse race at Belmont Park in Elmont, N.Y. on Saturday, June 7, 2008. A close inspection of his rear hoof shows one of his shoes coming loose. What happened during the Belmont remains a mystery to Big Brown's owner, Michael Iavarone, though pictures taken during the race show Big Brown running with a seemingly dislodged shoe on his right hind foot.
