Kieren Fallon has been banned from racing for 18 months by France Galop after testing positive for a banned substance following a race at Deauville in August 2007, according to reports.
Fallon appeared before the French racing authorities on Wednesday as they considered the case of the six-time champion jockey, whose B-test sample confirmed the original positive test for a banned substance.
The hearing was held at France Galop's headquarters at Boulogne-Billancourt in Paris.
Fallon failed the test after Myboycharlie's success in the Group One Darley Prix Morny at Deauville on August 19.
Fallon previously served a six-month suspension imposed by France Galop for testing positive for a metabolite of cocaine in June 2006.
He was recently acquitted along with five others of conspiracy to defraud Betfair customers by a jury at the Old Bailey.
His employers Coolmore stuck by him following his six-month ban and the jockey soon bounced back on his return in June this year, winning the Group One Pretty Polly Stakes at the Curragh on Peeping Fawn at the end of that month.
However, he was unable to ride in Britain at that time because of the court case, which cost him several big-race winners including the King George VI And Queen Elizabeth Diamond Stakes on Dylan Thomas.
Fallon is licensed in Ireland but the French suspension would apply worldwide.
"We are not going to make any comment on this issue at all," said the British Horseracing Authority's PR manager Paul Struthers
