Kingsbarns is an intriguing name among eight Aidan O'Brien-trained contenders in the Neptune Investment Management Great Voltigeur Stakes at York on Wednesday.
Last year's Racing Post Trophy winner, who still holds an entry in the Juddmonte International on the same day, has yet to race this season after suffering a setback when being prepared for a Classic challenge in the spring.
O'Brien had planned to work him after racing at the Curragh last Sunday but the quick ground there forced the Ballydoyle trainer to rethink that plan, although he reported the colt in fine form and progressing well.
The Coolmore team have a wealth of talent at their disposal, with Queen's Vase winner Leading Light another in the running for this St Leger trial.
Foundry, Sir Walter Scott and Hall Of Mirrors have also yet to run this term, while Fortify, Kingdom and Plinth are the other O'Brien confirmations.
One-time Derby favourite Telescope is in the field, as expected, with Michael Stoute seeking quick compensation following the colt's eclipse in the Rose of Lancaster Stakes at Haydock last week.
Cap O'Rushes won the Gordon Stakes at Goodwood for Godolphin and he is one of two possibles for the owners, along with Secret Number, who finished a close-up fifth in that race.
The pair are trained by Charlie Appleby and Saeed bin Suroor respectively.
The Gordon third Spillway could try his luck again for Eve Johnson Houghton, while Mutashaded, Nichols Canyon, Royal Skies and Willie The Whipper round out the list of 16 possibles.
