Trainer Andy Leung Ting-wah will face a stewards inquiry into a positive drug test returned by his sprinter Wishmaster on October 3 following confirmation yesterday of the presence of an anti-inflammatory drug. Almost three weeks ago, Leung was informed of test results from the Jockey Club's laboratory, which discovered phenylbutazone and its metabolites - oxyphenbutazone and gamma-hydroxyphenylbutazone - in the post-race blood and urine samples from Wishmaster after he finished second in the Henan Handicap. Leung exercised his right to have the unused B-portion of the blood and urine samples tested by an outside analyst and the results of these were revealed yesterday as confirming the original findings. Stewards yesterday advised Leung of the finding and the matter remains adjourned to a hearing date to be announced. The last horse in Hong Kong to test positive for the well-known anti-inflammatory phenylbutazone was Elephant Dance at Sha Tin on October 6, 2002. The Gary Ng Ting-keung-trained stayer's positive cost the trainer a $75,000 fine under rules dealing with his responsibility to present horses drug free for racing. The appeals by Douglas Whyte and Eddie Lai Wai-ming against recent careless riding charges are to be heard this afternoon. Whyte is serving time currently over his ride on Engineering Wonder at Happy Valley last Saturday week and is appealing against his two-day ban and $40,000 fine for an incident involving Bowman's Crossing the previous weekend. Whyte's appeal is to be heard at 2.30pm and Lai is to appear an hour later over his two-day ban and $10,000 fine, also handed down on October 17.
