George Washington will face 10 rivals as he bids for a Classic double in Saturday's Boylesports Irish 2000 Guineas at the Curragh.
Kieren Fallon, who partnered the Danehill colt to a two-and-a-half-length success in the Stan James 2000 Guineas at Newmarket, will again be at the helm as he targets yet another Group One success.
George Washington is one of four runners for trainer Aidan O'Brien, who also has Arabian Prince, Hurricane Cat and River Tiber.
Britain will be represented by Jeremy Noseda's Newmarket fourth Araafa and the Mick Channon-trained Yasoodd - although the latter may miss the race due to the likely testing conditions at the Irish venue.
Kevin Prendergast's Decado will try to extend his winning sequence to four in the mile event, while Dermot Weld saddles Golden Arrow.
The line-up is completed by the John Oxx-trained Caribbean, Jim Bolger's Heliostatic and John Murphy's Crookhaven.
