Aidan O'Brien has a formidable hand as he bids to win the Doncaster St Leger for a fifth time, with impressive Curragh trial winner Order Of St George joined by stablemates Bondi Beach and Fields Of Athenry.
Bondi Beach is set to cross swords once more with the William Haggas-trained Storm The Stars, which was a narrow victor when the pair clashed in last month's Great Voltigeur at York.
The home team is made up by David Brown's Medrano and Proposed from Richard Hannon's yard, while French trainer Mikel Delzangles has left in Vengeur Masque.
Ralph Becket's filly Simple Verse will be supplemented having won three of her last four starts - the most recent of which saw her running out an impressive winner of a Group Three prize at Glorious Goodwood.
The three-year-old had the option of taking on her own sex in Thursday's DFS Park Hill Stakes at the Town Moor track, but connections have decided to bid for Classic glory against the boys. Beckett said: "She worked very well on Saturday, she's had a number of tests done and all those came back A1 and we feel it's the right time to have a go and roll the dice."
Air Vice Marshal is O'Brien's sole remaining entry among 12 horses in contention for the Champagne Stakes on the same afternoon.
The master of Ballydoyle had a number of horses entered at the previous confirmation stage, but has whittled his team down to just one, with Air Vice Marshal an obvious contender having filled the runner-up spot in the Superlative Stakes at Newmarket in July.
The winner of that Group Two event, Richard Fahey's Birchwood, could also head to Town Moor this weekend.
Mark Johnston has a couple of potential representatives in Beaverbrook and Welford, while Emotionless is set to step up in class for Charlie Appleby following a most impressive debut at Newmarket a month ago.
