Tombstone has not been supplemented for the Stan James Champion Hurdle as connections have decided to instead run him in the Coral Cup at the Cheltenham Festival.Eddie O'Leary, racing manager for owners Gigginstown House Stud, ended speculation that the seven-year-old might be added to the field for Tuesday's showpiece at the confirmation stage by announcing Tombstone would be aimed at Wednesday's handicap hurdle.The Gordon Elliott-trained gelding caused an upset on his latest start when beating Jezki, the 2014 Champion Hurdle hero, in the Red Mills Trial Hurdle at Gowran last month."He'll go for the Coral Cup. We've got Petit Mouchoir in the Champion Hurdle," said O'Leary.
