Grandouet will have another crack at Hurricane Fly in Punchestown's Rabobank Champion Hurdle to determine whether he will commence novice chasing next year.
Trainer Nicky Henderson was left wondering what might have been after his horse fell when still appearing to be going nicely in Tuesday's Champion Hurdle at Cheltenham, eventually won by Willie Mullins' star.
It was only Grandouet's second start of the campaign and the trainer said on Saturday: "The Champion Hurdle was the missing race, so we'll definitely go to Ireland.
"We'll know whether to stay hurdling if we're good enough to give Hurricane Fly any sort of a fright there.
"If he's blatantly 10lb behind or anything like that, we'll know to go novice chasing next year, but we need to do that to find out this year. I don't think he's a two-and-a-half-mile horse."
