Casino Drive, now standing at stud in Japan (Blood-Horse Staff 1, 2012), was unable to race in the 2008 Belmont Stakes due to a stone bruise discovered in his left rear hoof. It was described as “very minor” (Blood-Horse Staff 3, 2008), however he did not recover in time to run. Although I cannot find the specific treatment used on his hoof, he did recover enough to race again later that year and the following year, placing 12th in the Breeders’ Cup Classic and 2nd in the February Stakes ("Casino Drive”).
