Frankie Dettori pledged to “rebuild his reputation” after he has served a six-month ban for taking a prohibited substance when riding in France.

Frankie Dettori’s failed test over a banned substance at Longchamp in September was not for a performance-enhancing drug, his solicitor has said.

Kieren Fallon is to appeal after being banned from racing for 18 months by France Galop after testing positive for a banned substance following a race at Deauville in August 2007.

French racing authority France Galop has suspended jockey Kieren Fallon for six months for testing positive for a prohibited substance.
