Illness has forced Michelle Payne to withdraw from Saturday's Shergar Cup meeting at Ascot.
Payne has a virus and will be replaced in the Girls team by English apprentice Hollie Doyle. The jockey left a media function in London on Friday complaining of feeling unwell and allegedly swearing at an Ascot official.
Payne said in a statement she was disappointed not to be able to ride.
"It is with great disappointment that because of a virus I have contracted since arriving in England, I find I am unable to ride in the Dubai Duty Free Shergar Cup competition today," Payne said.
"I saw the doctor yesterday and we had both hoped the medication prescribed would kick in, but unfortunately that has not been the case and I am not well enough to compete today.
"I had been looking forward to being part of this special event for a long time.
"Joining The Girls team had been had been a major goal of mine over the last 12 months, since missing the opportunity in 2016 due to injuries sustained in a fall last year.
"I would like to thank everyone for their support and encouragement and would love to return another time."
Payne is staying in England to ride Kaspersky for Jane Chapple-Hyam at Newbury next week.
