Corine Barande-Barbe is hopeful Cirrus Des Aigles has not suffered any lasting damage after pulling up lame following his tremendous victory in Saturday's Investec Coronation Cup at Epsom.
The eight-year-old clinched his sixth Group One triumph with a determined display under Christophe Soumillon, but it was soon clear all was not well and the Belgian rider quickly jumped off the gelding's back after passing the post.
Cirrus Des Aigles was sound enough to walk into the winner's enclosure and was able to travel home to Chantilly on Sunday morning.
X-rays have revealed the he has not suffered any serious injuries, much to his trainer's relief.
Barande-Barbe said: "He's back home, he's had a roll and he seems very happy.
"We think it was just a little problem and nothing too serious. He was really lame straight after the race, but was much better very quickly.
"He has had an X-ray already and there is a small shadow, but on the whole the report is not too bad, which is fantastic.
"He will have some more X-rays in a few days and we will know more at the end of the week, but he had some medication yesterday, he has not had any since and he seems well this morning."
While unsurprisingly non-committal over future plans for her pride and joy, Barande-Barbe does retain hope he will recover in time for fourth tilt at the Champion Stakes at Ascot in October.
"It is difficult to say at the moment, but I think I will probably give him one month or six weeks off and look to the autumn. We have to be careful with him," said the trainer.
"It is hard to say anything for certain, but, if he recovers well, in my opinion we could aim for the Champion Stakes, with maybe one run before, but we really will have to wait and see."
Reflecting on the Derby Day victory, Barande-Barbe said: "It was a really great experience and it was just a shame he had the little problem after the race.
"It was a great day and a great occasion and I was very impressed by the support of the English public."
