One North American invitee for the Cathay Pacific Hong Kong International Races on December 11 will be refused a start without setting foot in Sha Tin after testing positive to anabolic steroids. Jockey Club officials yesterday gave no indication of which horse would not now be coming for the showpiece after its connections appear to have miscalculated on the length of time for elimination of the steroid treatment. 'There is no mandatory testing of horses before they leave for Hong Kong - this was an elective test, conducted by the connections of the horse themselves, as we advise people to do,' said executive director of racing Winfried Engelbrecht-Bresges. 'If a horse arrives here and returns a positive test, the transport costs to Hong Kong and back will be borne by the connections rather than by the Jockey Club, so we do suggest that anyone with any doubts should test before commencing the journey. 'The connections of the horse in question, knowing it had received steroid treatment, felt it would have been clear by the day of racing. They now know from their elective test that it has no chance of being clear - they are being asked to stay home,' he added. Engelbrecht-Bresges said that this was not the only problem with runners from North America, where many drugs are permissible for use in races which are illegal elsewhere in the world, describing other cases as 'borderline'. 'This drug issue is something on which we will not compromise,' he said. In other news, Engelbrecht-Bresges said the club was confident that Japan Cup victor Alkaased and fellow European runners, Ouija Board and Warrsan, will arrive in Hong Kong later this week as scheduled. 'Obviously there is the concern of them coming through a tough race on Sunday and their trainers won't really be sure for a few days, but they are expected to arrive and then a decision to be made based on their well-being once in Hong Kong,' he said. 'I think the owner of the Japan Cup winner is quite keen to run at Sha Tin but the trainer would like to see how his horse is doing later this week.' Engelbrecht-Bresges said there would be an announcement today regarding the vacant slots in the Hong Kong Cup and the Vase, and any changes to the local or overseas representatives in the races. 'We have a very good standby for the Vase from France,' he said. 'However, we don't want to give the impression there must be 14 runners regardless. It will be on a basis of quality rather than quantity.'
