Derby winners Anthony Van Dyck and Sovereign are set to represent Aidan O'Brien in the King George VI And Queen Elizabeth QIPCO Stakes at Ascot later this month.
Japan was originally pencilled in for the Berkshire showpiece having landed the King Edward VII at Royal Ascot but will instead contest the Grand Prix de Paris next weekend.
Anthony Van Dyck won a thrilling Investec Derby at Epsom last month but subsequently couldn't reel-in front-running Sovereign in the Dubai Duty Free Irish Derby.
The trainer told ITV Racing: "I think the lads are thinking about going to France with Japan for the Grand Prix de Paris on Saturday week, that’s the plan at the moment.
“Anthony Van Dyck might go to the King George with the horse that beat him in the Irish Derby (Sovereign). Things could change and a lot of things have to go well between now and then.
"Japan had a bit more time between Ascot and France and the Irish Derby horses have more time before Ascot but we’ll discuss things on a daily basis and if the lads want to change it, we’ll change it.”
