INTERNATIONAL Bowl favourite Concert King is out for the rest of the season. The Derek Cruz-trained sprinter, Hongkong's top-rated horse, suffered a bleeding attack during trackwork at Sha Tin yesterday and is mandatorily scratched from next month's $3.5 million showpiece event. It is shattering blow to Cruz who, despite being under intense pressure since the public and acrimonious split with his brother Tony, has clung to a share of the lead in the trainer standings. The bleeding attack leaves multiple champion Irish jockey Mick Kinane, who had been scheduled to ride him in the Bowl, now lined up to partner Diamonds Galore for his retaining trainer in Ireland, Dermot Weld. Still shocked by yesterday morning's proceedings, Derek Cruz said last night: ''I know racing is a tough game with many more downs than ups but this really breaks my heart. ''We had all set our minds on trying to win the International Bowl for Hongkong. ''Concert King is the best horse I have ever sat on in all the time I have been connected with racing. He's something special. ''I will now give him as much time as he possibly needs to get over the attack and do everything in my power to bring him back next season as good as ever. ''In many ways it is typical of my season to date. I know I'm sharing the lead in the championship but since I broke with Tony there has been a hell of a lot of pressure on me. ''But that's racing. Life must go on. I will hold my head high and carry right on training as many winners for my owners as possible.'' Concert King's bleeding attack happened during a gallop from the gates at the top of the back straight in preparation for his International Bowl lead-up race, Sunday's ATV Cup. He had appeared to work fluently with stablemate Blue And Gold, covering a 400-metre mid-section in a smart 21.9 seconds. But he returned with blood appearing from one nostril, leaving trainer Cruz with no option under Jockey Club Rules but to report the incident to the veterinary department. Concert King is now sidelined for three months. Concert King is the latest of a number of good horses to suffer bleeding attacks. John Moore's much-vaunted Australian import, Fastabob, was a recent victim and there are many who argue that these problems are a direct result of the equine influenza virus which forced racing to close down last December. Keith Watkins, the Jockey Club's senior vet, was yesterday prepared to partially agree with this view. He said: ''It is very difficult to be specific. We won't be able to comment meaningfully until towards the end of the season when we will get a much clearer statistical picture. ''But yes, I will agree that at the moment there do seem to be more cases of horses being reported to have bled during trackwork. ''We did also say at the time that we thought this might happen. The 'flu is a respiratory virus and therefore affects the lungs.'' Watkins was also quick to praise trainer Cruz's actions, saying that he had followed the only course of action which may allow Concert King to eventually return to his best. ''If he had not reported him, not only would he be breaking Jockey Club Rules, he would also be putting the horse, the jockey and other jockeys and horses at risk,'' he said. Kinane is now waiting to hear from Weld about his plans for the Canadian-bred Diamonds Galore who finished third to Lyric Fantasy and the ill-fated Mr Brooks in last season's Group One Nunthorpe Stakes at York. ''Dermot has only had Diamonds Galore for about a month so I'm waiting to hear his plans,'' Kinane said yesterday. Should Diamonds Galore be scratched then Kinane will try to pick up the ride on Guy Harwood's Thourios, another top-flight European challenger.
