Ol' Man River heads a seven-strong representation from the Aidan O'Brien stable for the Juddmonte Royal Lodge Stakes at Newmarket on Saturday.
A leading Investec Derby contender, Ol' Man River cost 2.85million euro at Goffs and made the perfect start to his career when impressing in a maiden at the Curragh last month.
He also holds an entry in the Somerville Tattersall Stakes at Headquarters on Thursday and in the Juddmonte Beresford Stakes at the Curragh on Sunday.
O'Brien's other possibles for the Royal Lodge are Aloft, General Marshall, Jamaica, Order Of St George, Rule The Waves and War Envoy.
Sixteen acceptors remain in the Group Two contest over the Rowley Mile, including Elm Park, who has been supplemented by trainer Andrew Balding.
The Phoenix Reach colt was an all-the-way winner of the Listed Stonehenge Stakes at Salisbury on his latest start.
Richard Hannon is double-handed with Lexington Times and Misterioso, while the list is completed by Cock Of The North, Lord Ben Stack, Medrano, Nafaqa, Prince Gagarin and Salateen.
