Frankel features among 12 possibles for the Queen Anne Stakes at Royal Ascot on Tuesday.
Henry Cecil's brilliant colt has swept aside everything put before him in his career to date, and seeks to take his unbeaten run to 11 in the Group One over the straight mile that brings the curtain up on the five-day meeting.
Excelebration, who has been well-beaten four times by Frankel, including in the Lockinge Stakes at Newbury last month, takes on his nemesis again.
His trainer Aidan O'Brien has also left in multiple Group One winner So You Think at the five-day stage, as well as Windsor Palace.
Frankel's half-brother and regular galloping companion Bullet Train is among the dozen as are Strong Suit, Premier Loco, Side Glance and Red Jazz.
Andreas Wohler's Indomito represents Germany while Worthadd and Helmet make up the entries.
