Aidan O'Brien will fire a three-pronged assault at the Tattersalls Gold Cup in a bid to win the Group One prize for a record seventh time at the Curragh on Sunday.
Brilliant filly Minding was due to be O'Brien's main hope for this year's renewal, but a setback has ruled her out of the race.
The Ballydoyle handler instead relies upon recent Huxley Stakes winner Deauville, Johannes Vermeer and Somehow, who turns out just eight days after finishing fourth in the Lockinge Stakes at Newbury.
It will be Somehow's fourth appearance in less than a month.
Roger Charlton, who won the Tattersalls Gold Cup twice with Al Kazeem (2013 and 2015), is represented by Group One scorer Decorated Knight, the only British representative in the eight-strong field.
Success Days was considered unlikely to run earlier in the week but he has now been declared by Ken Condon.
The Jim Bolger-trained Moonlight Magic, Joseph O'Brien's Reckless Gold and Gentil J from Harry Rogers' stable complete the line-up.
