Jockey Frankie Dettori has suffered an injury scare a week before Royal Ascot.
The 46-year-old Italian was stood down for the day after a fall before the opening race at Great Yarmouth.
Dettori, the most successful Royal Ascot jockey currently riding, was due to ride Tivoli for trainer John Gosden in the six-furlong fillies' maiden when he was unshipped in the parade ring.
Tivoli was withdrawn and Dettori, who left nursing his shoulder, did not ride Falak in the following race.
Dettori, who has ridden 56 winners at Royal Ascot, was thrown to the ground after Tivoli seemed to be startled.
"The doctors have told me they have looked at him and how he is and they are happy for him to go home," said Yarmouth clerk of the course Richard Aldous.
The incident came seven days before the start of the Royal Ascot meeting, where second favourite Vazirabad has been ruled out of the Gold Cup with a leg injury.
