Giant's Causeway will face seven rivals in Saturday's Entenmann's Irish 2000 Guineas at the Curragh following today's final declaration stage.
The Aidan O'Brien-trained colt, three-and-a-half lengths second to King's Best in the Newmarket equivalent, is set to clash again with Barathea Guest, Cape Town and Scarteen Fox, third, 12th and 19th respectively on the Rowley Mile.
And the relative strength of British and French Classic form will be tested with Godolphin's French 2000 Guineas winner Bachir taking his place in the line-up.
Frankie Dettori will ride Bachir with Johnny Murtagh taking the mount on Godolphin's other runner Glad Master.
Although easy ground is in Barathea Guest's favour, trainer George Margarson is concerned that a mile may be too sharp for his charge.
Margarson told Sky Sports on Wednesday: "A mile is as short as he ever wants, even though the ground will be in his favour.
"It's shaping up as if there will only be about eight in the race and I'm worried about the pace for him.
"But we'll get the race over and then we can have a right crack at the Derby with him."
The only withdrawals from the race were Giant's Causeway's stablemate Bach, who is likely to go for the Prix Jean Prat at Chantilly next month, and the Kevin Prendergast-trained Shibl.
Following an eighth of an inch of rain overnight, the going at the Curragh is described as yielding, yielding to soft in places on the straight course.
Cape Town, winner of the European Free Handicap at Newmarket in April, had been expected to go for either Saturday's sportingodds.com Euro 2000 Heron Stakes at Kempton or the Jersey Stakes at Royal Ascot next month.
Trainer Richard Hannon explained: "It was the owners who wanted a change and decided they wanted to run him in Ireland.
"I must say I didn't realise the race was going to cut up and he will have a good chance of running into a place. It's well worth running in a Group One if you can get in the first three."
Hannon said Dane O'Neill was riding because Richard Hughes, who has ridden the colt on both his starts this season, had a full book of rides in England.
But he added: "I'm sure Dane will do a good job anyway." - PA
