The legendary 22-times scorer at the top level, including two Champion Hurdles, would be making his first appearance on Merseyside at the age of 11.
His trainer Willie Mullins has also put in Arctic Fire, who ran a tremendous race to finish one place ahead of Hurricane Fly when second to stablemate Faugheen in this season’s renewal of the Cheltenham showpiece.
Jezki, who was fourth that day, has been given the entry by Jessica Harrington and Colin Bowe’s mare Little King Robin is the other Irish-trained possible.
Harry Fry’s Rock On Ruby is in line to run in the race for the second successive year after being forced to miss Cheltenham.
The 10-year-old missed the World Hurdle with a slight setback but is bang on course for Liverpool.
However, whether he runs in the race in which he was so narrowly beaten last year by The New One or the three-mile Liverpool Hurdle has still to be decided. The Dorset handler said: “I am pleased to report Rock On Ruby is bang on course for Aintree after recovering from the bug that caused him to miss the Ladbrokes World Hurdle at Cheltenham.
“We immediately put him on a course of antibiotics which seemed to do the trick and he has been pleasing in his work again over the last fortnight.
“We were hoping to take Ruby away for a racecourse gallop this week but fast ground put paid to that plan. So this morning Noel Fehily came down to sit on him and was clearly delighted with his well-being.
“We feel that Ruby is back on his A game which is good news with Aintree round the corner.
“He will hold an entry on the opening day in the Grade One Aintree Hurdle in which he was a close second to The New One a year ago. But I will also give him an entry in the Grade One three-mile hurdle on Grand National day. Early next week I’ll have a close look at both races before choosing between them.”
Paul Nicholls has two sound chances in World Hurdle third Zarkandar, winner of this race two years ago, and French import Aux Ptits Soins, who won the Coral Cup at Cheltenham.
