Galway Hurdle favourite Petrol Head withdrawn after positive sample emerges

There was high drama at Galway on Thursday morning as was withdrawn from the €270,000 Guinness Galway Hurdle by the Irish Horseracing Regulatory Board. 

The eight-year-old had attracted significant support having been available at 16-1 overnight, and was the general 6-1 favourite at the time of his withdrawal.

It emerged that Katy Brown's charge had tested positive for a prohibited substance when winning at Bellewstown on July 6, but the IHRB only received confirmation at 11am this morning.

Irish Horseracing Regulatory Board CEO, Darragh O'Loughlin, spoke with Fran Berry live on Racing TV to discuss an "unprecedented set of circumstances" as our top presenter asked all the key questions about the dramatic incident.
