Nicky Henderson admits there must be a question mark over Oscar Whisky’s ability to stay the World Hurdle trip.
The seven-year-old finished third in last year’s Champion Hurdle before winning the Aintree Hurdle over half a mile further, prompting connections to step up to the staying races.
Henderson said: “He’s not a Champion Hurdle horse. I know he was third last year and he’s improved a bit as well, but we’ve got to try this race.
“He’s very good, in really good shape and it’s all a matter of if he stays.
“If he does, then we’re capable of giving Big Buck’s a race.”
