Six-time champion flat jockey Kieren Fallon has been fined £3,140 by the British Horseracing Authority after failing to arrive in time to take his first two rides at Chester on 5 May.
Fallon, 46, was fined £3,000 for misleading a steward and £140 for not informing the clerk of course as soon as possible he would not make rides.
He missed the rides after arriving more than an hour-and-a-half late.
The Irishman said he was stuck in traffic and had a flat phone battery.
Fallon failed to take the rides on Fred Willetts and Forte Dei Marmi.
It is the latest episode in the controversial career of Fallon, who has won the Epsom Derby three times but was prevented from riding in the race in June after the owners of Native Khan obtained an injunction against him, claiming he had reneged on a deal to ride for them.
