Alive Alive Oh will face nine rivals as she attempts to make up for missing the Ribblesdale at Royal Ascot last week in the Oxigen Environmental Pretty Polly Stakes at the Curragh on Sunday.
Trained by Tommy Stack, the three-year-old has created a good impression in her two races this season and was set to go off favourite at the big meeting before connections pulled her out on account of the fast ground.
She will come up against last year's Oaks winner Was, trained by Aidan O'Brien, who also runs Say.
Princess Highway was an impressive winner of last season's Ribblesdale for Dermot Weld and was third in the Irish Oaks, although she is without a win since that day at the Royal meeting.
Roger Varian sends over Ambivalent from his Newmarket base and she will be joined by Hughie Morrison's Shirocco Star, second to Was at Epsom last year.
Mick Channon's Cruck Realta is another British challenger while Kevin Prendergast runs La Collina.
John Oxx is represented by Harasiya and Jim Bolger runs Rehn's Nest, second in the Irish 1,000 Guineas but well beaten in the Coronation Stakes last week.
Stack's son and assistant, Fozzy, feels Alive Alive Oh has recovered from the exertions of travelling to England and back without a problem
"She seems well enough after it, anyway," said Stack.
"That was the first time she'd ever had a journey of any real length but she took it all in her stride, thankfully. It was just a shame she couldn't run.
"It will be a long time before we scratch a favourite at Ascot again, I can say that.
"But the owners are very understanding and they want her for a long time, not just a good time. The ground was very hard at Ascot so it was the correct decision, we feel, anyway.
"She seems well, she's taking on the older fillies but she seems well and I don't think I'd swap her for anything in the race. She should have a very good chance."

Jockey Joseph O'Brien is expecting a much better show from Was stepping back up in trip after her seasonal reappearance where everything appeared to be happening too fast over a mile.
"She ran a nice race at the Curragh earlier on in the year over a mile and that trip is probably a bit short of her best," O'Brien told At The Races.
"She's stepping back up to a mile and a quarter here so we'll be hoping for a good run."
Hughie Morrison would have preferred to have seen more rain for Shirocco Star, who is another stepping back up in distance after a run over a distance short of her optimum.
"Ideally she would have wanted a bit more rain to be seen at her best," said Morrison.
"I know she has run well on fast ground before, it was quick enough in the Oaks, but I just feel that she's better with a little bit of ease.
"Her best form entitles her to win this race but people keep telling me that and she hasn't managed to win one yet."
One dropping down in trip is another of the British raiders, Roger Varian's Ambivalent, who has run two solid races in Group company this term but is stepping up in class.
"Ambivalent has bags of ability and has run two solid races this season. Judged on her run in the Middleton Stakes, I think the drop back to ten furlongs will suit. We would be delighted if she can run in the first three," Varian told www.varianstable.com
