The son of Galileo, who bids to join an illustrious band of colts to complete the Guineas double, has been allotted stall two and will again be ridden by Ryan Moore.
O’Brien also saddles Smuggler’s Cove (Seamie Heffernan) and The Warrior (Joseph O’Brien) as he attempts to land the prize for a record 10th time.
Ivawood, who finished third behind Gleneagles at Newmarket, renews rivalry.
Richard Hannon’s speedy colt is joined by stable companion Lexington Times.
There is a third British challenger in the Roger Varian-trained Dewhurst winner Belardo, who disappointed on his seasonal debut in the Greenham Stakes at Newbury last month.
Ger Lyons is double-handed with Convergence and Endless Drama, with the list completed by Carbon Dating, Mohaayed and Tombelaine.
Meanwhile Sole Power will have his first run on home soil since August 2011 in the Weatherbys Ireland Greenlands Stakes, also at the Curragh tomorrow
Eddie Lynam’s globetrotting star last ran in Ireland in the Flying Five Stakes at the Curragh when second to Amour Propre.
He also had the option of the Temple Stakes at Haydock, a race he won in 2011, on the same day, but the Curragh is the venue of choice.
What also worked in the Curragh’s favour is that regular rider Richard Hughes is in Ireland this weekend to ride Ivawood in the Tattersalls Irish 2,000 Guineas.
Lynam said: “We want to run this weekend.
“The ground at the Curragh is good to yielding and I am happy with that. (We’re also) keen to run in Ireland after so long.”
Sole Power has taken his connections all around the world and Paddy Power, spokesman for the bookmakers of the same name whose parents own the sprinter, said: ‘‘We decided this weekend the best option was to run at the Curragh,
“We’d spoken to somebody who walked the track at Haydock and the ground is just a bit softer there so it’s going to be more suitable at the Curragh.
“Richard Hughes will be at the Curragh, too.”
Rebel Fitz is likely to be ready for a return to action at Listowel in September.
Trainer Michael Winters has one eye on the mile-and-three-quarter Flat race his classy and versatile performer won last autumn as the probable starting point.
Though Rebel Fitz is back in light work after recovering from the injury that has kept him off the track since he won the Grade Two Istabraq Hurdle at Tipperary last October, Winters feels time is against the 10-year-old being ready for the Galway Festival in late July and early August.
“He’s very good and is just starting back in work now. We are probably a little bit behind schedule,” said the Cork handler.
“I think Galway will come a fraction too soon for us so he may go back to Listowel. If he’s qualified, he’d go for the race he won last September.
“It would be a great race to win again as it’s on the Flat and there are no stalls.
“That race may be ideal for him. He’d be right by then because he’s doing road-work now and he’s cantering.
“We’re delighted with him and he’s been running around in the field as well.
“Everything is good. The little bit of swelling he had below the joint has gone.”
