Finian's Oscar has been ruled out of the Cheltenham Festival due to a minor setback.The five-year-old was among the leading lights for the Neptune Investment Management Novices' Hurdle after winning each of his three hurdles starts this term, including the Grade One Tolworth at Sandown in January.However, trainer Colin Tizzard reports his charge to be suffering from a small issue which will see him miss out next week, although he is hoping Finian's Oscar will be ready to run at Aintree next month.Tizzard said:"Unfortunately Finian's Oscar will miss Cheltenham due to a minor setback. It's only a minor issue and all being well he will run at Aintree."
