Ruler Of The World will face eight rivals as he bids for a Classic double in Saturday's Dubai Duty Free Irish Derby at the Curragh.
Aidan O'Brien's colt won the Derby at Epsom on just his third start, having been unraced as a juvenile, and will clash again with the placed runners from that day.
Epsom second Libertarian will have his final start for Elaine Burke after being bought by Godolphin, while David Wachman's Galileo Rock will try to improve on his third place.
Libertarian was supplemented for the race earlier in the week along with Godolphin second-string and likely pacemaker Cap O'Rushes, who is trained by Saeed bin Suroor.
Another contender having his final run for his current stable is Patrick Prendergast's Sugar Boy, winner of the Sandown Classic Trial in April. He was purchased by Sheikh Mohammed Bin Khalifa Al Maktoum on Tuesday and will move to an as yet unspecified trainer after this race.
Jim Bolger will be represented by Trading Leather, second in the Dante to Libertarian and third in the Irish Guineas, while John Oxx runs Little White Cloud.
O'Brien, who has won the last seven renewals of the race, also runs Festive Cheer, while Pat Shanahan's Ralston Road, eighth in the Queen's Vase last week, completes the field.
Racecourse manager Paul Hensey said: "We had a bit of rain at the weekend and just under 3.5mm this morning and I reckon we'll be starting the meeting, certainly on the straight course, on good ground.
"It's a cracking race, you can make a case for five or six with the first three from Epsom, Trading Leather, Sugar Boy and Little White Cloud."
