Racing Victoria stewards have received a report from the RASL confirming that a prohibited substance has been detected in a urine sample collected from Darragh who is trained by Terry and Karina O’Sullivan.
A pre-race urine sample was taken from Darragh prior to running in the McKellar Mile at Ballarat on 21 November, 2015, in which the horse finished fifth.
Trainers Terry and Karina O'Sullivan have been advised of cobalt positive regarding horse Darragh. We'll have more information shortly.
