High Definition is among 18 confirmations for Thursday's Al Basti Equiworld Dante Stakes at York.
Aidan O'Brien's unbeaten colt lost his position at the head of the ante-post market on the Cazoo Derby after an unsatisfactory blood test earlier this week.
O'Brien had intended to run the son of Galileo in Saturday's Derby Trial at Lingfield, but there is a chance he could reappear on the Knavesmire should all go well in the meantime, with the Ballydoyle admitting it would be "very hard" to go to Epsom without a prep race.
O'Brien has also left in Hector De Maris, Matchless, Roman Empire, Sir Lamorak, Van Gogh and Wordsworth.
One trainer who has always had this race in mind for his Derby hope is Mark Johnston with Gear Up.
The only Group One winner left among the potential field having won the Criterium de Saint-Cloud over 10 furlongs last year, Gear Up will be making his seasonal reappearance.
"All is well. The Derby seems to be quite wide open, but no one seems to be talking about us!" said Johnston.
"He's a Group One-winning two-year-old with York form.
"He's only got one blot on his copybook when Franny (Norton) felt he didn't make enough use of him in the Royal Lodge.
"Franny is the only one to be beaten on him, but I wouldn't hold that against him as he told us as much about the horse as anybody. I don't know who rides him next week yet."
John Leeper, one of the most beautifully-bred horses in training being by Frankel out of Snow Fairy, will aim to build on his impressive Newcastle success for Ed Dunlop.
Charlie Appleby's Hurricane Lane is another unbeaten contender, with stablemate Adayar also standing his ground, although he is declared to run at Lingfield on Saturday.
John and Thady Gosden could be doubly represented by Newcastle Listed winner Megallan and Uncle Bryn, who lost his perfect record in the Blue Riband Trial at Epsom.
William Haggas' Alenquer, the Sandown Classic Trial winner, may also run.
On the same card is the Al Basti Equiworld Dubai Middleton Stakes, for which nine remain.
Jessica Harrington can call upon Cayenne Pepper and Silence Please, while O'Brien's sole representative is Passion.
Chamade (Ralph Beckett), Cabaletta (Roger Varian), Bharani Star (Peter Chapple-Hyam), Freyja (Johnston), Oriental Star (David Simcock) and Queen Power (Sir Michael Stoute) complete the list.
