Jockey Frankie Dettori faces a six-month ban from riding when the stewards of France Galop meet in Paris today.
The Italian tested positive for a prohibited substance at Longchamp on September 16 and last month the medical commission of the French racing authority passed its findings to the stewards for their consideration.
Dettori was temporarily suspended from riding in France with immediate effect on medical grounds and his solicitor, Christopher Stewart-Moore, issued a statement saying the 41-year-old accepted their conclusions "without reservation". The jockey had four rides at the Prix de l'Arc de Triomphe trials meeting on September 16, after which the sample was returned.
Dettori made the headlines in October when his 18-year association with powerful owners Godolphin came to an end, with the three-times champion jockey planning to ride as a freelance in 2013. Any ban could be recognised by racing jurisdictions worldwide.
Wolverhampton's all-weather cards on Thursday, Friday and Saturday have been abandoned. This afternoon's fixture will go ahead, but temperatures are set to fall later in the week.
Last Saturday's evening meeting at Wolverhampton was abandoned after just three races when jockeys raised concerns about the Polytrack surface balling under the horses' hooves once temperatures dipped.
Thursday's meeting at Wolverhampton was a twilight fixture, while Friday's and Saturday's cards were due to be on in the evening.
As a result, the British Horseracing Authority (BHA) have transferred fixtures on Thursday, Friday and Saturday to Lingfield, though Friday's card has been switched to Sunday due to Lingfield already racing that day.
Lingfield will also play host to Wolverhampton's card next Tuesday, a meeting which was originally transferred from flood-hit Southwell.
