Irish gelding One Won One tested positive to two prohibited substances after he won the Listed Halliwell Landau John Of Gaunt Stakes at Haydock Park in June, it was revealed today.
The Horserace Forensic Laboratory reported that the analysis of the sample taken from the Joanna Morgan-trained gelding has confirmed the presence of phenylbutazone and oxyphenbutazone.
An inquiry will be held by the Jockey Club`s disciplinary committee in due course.
