American Aaron Gryder will make his debut in next month's Dubai Duty Free Shergar Cup along with promising Hong Kong jockey Matthew Cadwick and Italian champion Cristian Demuro.
Gryder and Cadwick will be part of the Rest of the World side in the team jockeys' competition at Ascot on August 11, which will be captained by Japanese legend Yutaka Take.
Gryder, a Dubai World Cup winner, has not ridden in Britain since 1992, while Chadwick will be spending a few weeks with Charlie Hills in Lambourn later this month.
German ace Andreas Suborics will be involved in the European team along with Demuro, the younger brother of jockey Mirco, and Frankie Dettori, if available.
The line-up for the Great Britain & Ireland male team will be announced closer to the event, against the first all-female team, made of up Hayley Turner, Chantal Sutherland and Emma-Jayne Wilson.
Nick Smith, head of communications for Ascot, said: "This promises to be the most exciting Shergar Cup in the event's history, with the first all-female team and more international jockeys taking part than ever before, some legends in their own countries and some who are rapidly rising young stars."
