Casino Drive (Mineshaft), the horse pegged most likely to stymie Big Brown's Triple Crown bid, may be forced to miss Saturday's GI Belmont S. The chestnut colt did not go to the track Friday morning because connections were concerned with a potential injury to his left hind leg. “We were not happy with the way his hind leg was moving,” Nobutaka Tada said. “That's the reason he didn't go to the track.” The problem has not yet been diagnosed, and it has not yet been determined if the three-year-old will be able to run in the Belmont. “We will see how he is [Saturday],” Tada said. “I can't say anything more right now.”
