Top-class filly Sea Of Class is reported to be making progress in her fight against life-threatening illness.
But trainer William Haggas warned that recovery from the bout of colic that forced her into retirement this month will be a long process.
The four-year-old was one of the stars of 2018, when she won the Irish Oaks and Yorkshire Oaks and went very close to denying Enable a second Prix de l'Arc de Triomphe.
But the day after her old rival's Eclipse Stakes victory, it was revealed that her own racing career had been ended and she was receiving intensive care following a colic operation.
The Tsui family, who own Sea Of Class, hope to save her for stud and Haggas said on Thursday: "She's making a little bit of progress.
"Like all doctors, vets are very keen not to give us too much encouragement but we feel she's looking much brighter. It's good news but I'm afraid there's still a long way to go."
Haggas also reported that Maqsad, the forgotten filly from last month's Investec Oaks, is firmly on the comeback trail and could reappear in the Qatar Nassau Stakes at Goodwood.
The Pretty Polly Stakes winner started third favourite at Epsom only to trail in eighth, with the step up to a mile and a half widely blamed for her finishing position.
She has not raced since but Haggas said: "She's in great form, she's working this weekend and then we'll make a plan for her, but she's not far away. We're very happy with her. The Nassau is a possible, it's very much in the calculations."
Maqsad would be dropping back to a mile and a quarter at Goodwood but Haggas is not convinced that her Oaks performance can be put down entirely to lack of stamina.
"She stopped very quickly at Epsom so we thought it was a little bit more than the trip," he said. "She stopped too quickly, having travelled as well as anything with two to run.
"She came back and was pretty tired after and was out of sorts for a while but she's fine now and in good form."
