Trainer Charlie Hills told the Racing Post: "She had a canter this morning and came home sound but just as I was about to go to Newmarket I was told she was lame behind.

"She has x-rayed and scanned clean, which is a good sign, and I would think she has picked up some kind of little infection in her hock."

David Redvers, racing manager to Qatar Racing, said: "Kiyoshi came off the gallops fine, but a small infection seems to have developed in her hock. Whether she will be back in time for the French Guineas I don't know."

Alutiq has also been withdrawn from the QIPCO-sponsored fillies' Classic, but Redvers said: "It is disappointing, but we still have Lightning Thunder in the race."
