Diamond Jubilee Stakes winner Dream Of Dreams is expected to miss the rest of the season after suffering a recurrence of an old injury, but should be back in action next year.
Sir Michael Stoute's seven-year-old has been affected by the return of ankle problem which has forced him to miss Saturday's Darley July Cup at Newmarket.
Dream Of Dreams was not given an entry in the Sprint Cup at Haydock in September, which he won last year, suggesting connections are resigned to him being sidelined for the rest of 2021.
"He's obviously missed the July Cup. He's very sore and will probably be out for the season," said Bruce Raymond, racing manager to owner Saeed Suhail.
"It's not a serious injury. It's a small one, but a bad one for a sprinter. It's the recurrence of an old ankle injury.
"He'll be coming back next year definitely - he's a gelding.
"Winning at Ascot was the main one."
