Aidan O'Brien has made his usual strong entry for the Juddmonte International at York, headed by Hardwicke Stakes hero Await The Dawn and ex-Australian star So You Think.
The master of Ballydoyle has entered a total of 15 horses, including St Nicholas Abbey, Zoffany and Misty For Me.
Frankel is one of the headline names among the 43 entries for the ten-furlong Group One contest.
Sir Henry Cecil's three-year-old star is now undefeated in seven starts, including victories in the 2000 Guineas and St James's Palace Stakes on his last two outings.
However, he has yet to race beyond a mile and would be a fascinating contender if he lines up on the Knavesmire.
Frankel is owned by Khalid Abdullah and he also has multiple Group One winners Midday, Workforce and Twice Over among his other possible challengers.
Godolphin are another team with plenty of possibles, with Prince of Wales's Stakes winner Rewilding in the squad.
