William Buick has been handed a four-week ban by the Chantilly stewards after an incident in the Prix de Diane.
Buick, on Highlands Queen, was adjudged to have caused the fall of Pierre-Charles Boudet's mount Armande.
He was subsequently disqualified from his ninth-placed finish and put last.
During the inquiry the stewards banned Buick the automatic 15 days for causing the fall, however, Godolphin's jockey was handed an extra 15 days for being offensive to the officials.
Buick has stated his intention to appeal the original 15-day suspension.
The ban is due to begin on 3 July.
If he is unsuccessful in his appeal he will miss meetings such as the Irish Oaks and King George VI And Queen Elizabeth Stakes at Ascot.
