KAUTO STAR INJURY WORRY Several bookmakers have suspended betting on the Cheltenham Gold Cup following worries of an ankle injury to favourite Kauto Star. The horse was found to be lame following his easy victory at ascot on Saturday and his leg is due to be scanned on Sunday. On betfair the horse´s price drifted to over 5/1, but has since shortened back to 11/4 with stablemate Denman now the clear favourite.
