Estimate, The Queen's 2013 Ascot Gold Cup winner, is among 15 entries for the Artemis Goodwood Cup on Thursday.
The mare has been at the centre of the morphine controversy that has shocked racing this week.
However, trainer Sir Michael Stoute is still allowed to make entries for the five-year-old despite her failing a drugs test, which is believed to be down to contaminated feed, after finishing second in last month's Gold Cup.
As expected, last year's winner Brown Panther features after connections decided not to take the Tom Dascombe-trained six-year-old to Ascot for Saturday's King George VI And Queen Elizabeth II Stakes.
Ahzeemah, runner-up last year, is in the mix again, while owners Godolphin and trainer Saeed bin Suroor also have Princess of Wales's Stakes victor Cavalryman and Excellent Result as possibles for the two-mile Group Two.
Owner Marwan Koukash can choose from his Chester Cup winner Suegioo and Northumberland Plate scorer Angel Gabrial, while Talent, who took last year's Investec Oaks, has been given an entry.
Aidan O'Brien's Eye Of The Storm is the only Irish-trained horse in the list.
Missunited, who was just behind Estimate in third place in the Gold Cup, is a surprise omission.
Michael Winters' versatile mare is set to run in the Group Three Sterling Insurance Lillie Langtry Stakes on the same card instead.
Winters said: "I wouldn't mind seeing a bit of rain in Goodwood to take the sting out of the ground, but she goes on good ground perfectly well."
