Roderic O'Connor could make his return to action in the Leopardstown 2,000 Guineas Trial Stakes on Sunday.
Aidan O'Brien's colt got closest to Frankel in the Dewhurst last autumn before a successful raid to France which saw him secure the Group One Criterium International at Saint-Cloud.
Among the potential opposition is Kevin Prendergast's Anglesey Stakes winner Dunboyne Express, who went on to finish fifth in the Racing Post Trophy behind Casamento.
Prendergast also has Mawaakef in the mix, with Exodus and High Ruler adding strength to O'Brien's hand.
A Word Apart, Cocozza, Imperial Rome and Whipless complete the list of possibles.
O'Brien's dual Group One winner Misty For Me appears among 21 entries for the 1,000 Guineas Trial Stakes.
The daughter of Galileo won the Moyglare Stud Stakes before tasting success in the Prix Marcel Boussac across the Channel at Longchamp on Arc day.
The three-year-old is one of five entries for the master of Ballydoyle, with Empowering, Juliet Capulet, Together and Wild Wind also engaged.
John Oxx could be represented by course winner Manieree, Curragh scorer History Note and Naas winner Redskin Dancer, while Dermot Weld is able to call on Midnight Music and Zaminast.
Deire Na Sli, Gossamer Seed and Seeharn are other interesting contenders.
