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 Sir 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.
Roger Varian's Mutashaded will gallop over the next couple of days before his participation is confirmed.
Lightly-raced, he was last seen finishing third behind Hillstar in the King Edward VII Stakes at Royal Ascot on just his third start.
Owner Hamdan Al Maktoum's racing manager Angus Gold said: "The Great Voltigeur has always been the plan.
"Roger will just check his well-being this weekend before committing him to the race.
"He's had one or two disappoint a little of late so he just wants to make sure.
"He'll probably work on Friday or Saturday and then make a decision.
"Roger also has Elkaayed who ran in the Gordon Stakes so he'd have a bit of a line through him.
"This looks the right race and he has been in good form since Ascot."
