It would have been Rosanara's first journey outside France, but she took on an injury loading onto the plane.
Irish racing manager Pat Downes, for owner the Aga Khan, said, "She got a bit upset when she boarded in France and unfortunately she got a knock which will prevent her from running tomorrow.
"It doesn't appear too serious and hopefully she will be OK."
Rosanara's withdrawal means 15 starters are now set to contest in the Group One fillies event.
Included in the 15 contenders is King's Vintage, as she takes a huge jump from handicap company to bidding for Classic glory in the short time of five days.
Tom Mullins her trainer thinks it is worth taking a chance with her after her victory at Killarney on Tuesday by four and a half lengths.
"She's come out of the race very well, she's progressing and we're just hoping for the best," said the trainer.
"Any more rain would help her cause and she stays well.
"Fran (Berry) rode her the other day and was very quick to learn about her and we're very glad to have him. He told us a few things about her after he rode her the other day."
Aidan O'Brien states that Remember When in great form as she bids to come back from a disappointing run in the Pretty Polly Stakes.
"She ran well in the Oaks at Epsom but we were a little bit disappointed with her back here in the Pretty Polly, for what reason we're not sure," he said.
"She seems to be in good form and if she came back to her Epsom form, we'd be really looking forward to her running.
"We think the Curragh will suit her well and she's in good form."
