Last year's winner Rite Of Passage is the major absentee for the Gold Cup at Royal Ascot on Thursday following the confirmation stage.
Dermot Weld's seven-year-old was a creditable third behind Fame And Glory on his seasonal reappearance at Leopardstown, but Weld revealed earlier this week he had suffered a setback.
Aidan O'Brien's Fame And Glory takes top billing among 16 entries, with connections of Blue Bajan taking the decision to supplement him at a cost of £25,000.
John Gosden's Duncan looks a big danger to the Ballydoyle hope, while Kasbah Bliss and Brigantin are two possible challengers from France. Veteran Geordieland has also been entered, while Holberg, Opinion Poll and The Betchworth Kid are other possible runners.
Henry Cecil confirmed Midday is being targeted at the Pretty Polly Stakes at The Curragh following her Coronation Cup second place.
