Excelebration and So You Think remain on course for a clash with Frankel in the JLT Lockinge Stakes at Newbury on Saturday May 19.
The trio feature among the 14 horses still engaged in the Group One contest at the latest forfeit stage.
Frankel is due to work at Newmarket on Saturday as Sir Henry Cecil plots his return to action and he could be joined in the field at Newbury by stablemates Bullet Train and Jet Away.
Aidan O'Brien, trainer of Excelebration and So You Think, has also left Windsor Palace in the race while Charles Hills could be double handed with Ransom Note and Red Jazz.
Richard Hannon is another with two entries, Dubawi Gold and Strong Suit, while Saeed bin Suroor and Godolphin rely on African Story and Saamidd.
Worthadd and Nahrain complete the field.
