Norman Williamson has been booked to ride Irish challenger Sunset Lodge in the Red Square Energising Champion Hurdle Trial at Haydock Park on Saturday.
County Limerick trainer Charles Byrnes will drive his stable star over to Britain himself tomorrow.
Byrnes said: "This is a big step up in class but we'll know where we stand with him afterwards.
"We were offered big money for the horse by a couple of English trainers but we turned them down."
The eight-year-old was a 15-length winner of the Fitzpatrick Castle Hurdle at Leopardstown earlier this month.
