Earlier today the Stewards were advised by Dr T S M Wan, the Club’s Head of Racing Laboratory, that a pre-race urine sample taken from a horse entered to run in tonight’s racemeeting was found to contain the prohibited substance phenylbutazone and its metabolite oxyphenbutazone. It was established that the pre-race urine sample was taken from MIDNIGHT RATTLER trained by Mr J Moore. The Stewards ordered for a further urine sample to be taken from MIDNIGHT RATTLER under post-race conditions. Dr Wan subsequently informed the Stewards that preliminary analysis of the second urine sample confirmed the presence of phenylbutazone and its metabolite oxyphenbutazone. The Stewards acceded to a request from Mr Moore to withdraw MIDNIGHT RATTLER from this race. Accordingly, MIDNIGHT RATTLER was withdrawn by order of the Stewards. The matter was adjourned until a date to be fixed.
