CHARMING Talker is out of Sunday's $3.5 million Hongkong Derby in a massive blow to the race and the Patrick Biancone stable. The French trainer confirmed last night that his exciting New Zealand import would take no part in the Classic because of a tendon injury. And in further drama at Happy Valley last night, champion-elect Tony Cruz was taken to hospital with a shoulder injury after a fall in the first race. His mount, Rare Encounter, fly-jumped as the gates opened and although Cruz managed to hang on by one rein, he hit the ground about 30 metres out as the horse got into his stride. However, Cruz who is due to ride Happy Guy in the Derby is hopeful of being fit for Sunday. The blow to Biancone came just after Charming Talker had worked excellently at Sha Tin on Tuesday morning. The tendon injury came about following the removal of a shoe. Said Biancone: ''It is very disappointing but there is nothing I can do about it. The horse will not be fit to race for three weeks. ''He was in great shape and I must honestly say that I thought we could win it. But that is racing. ''There will be other Derbys, but the one on Sunday was the one I wanted to win,'' he said. In the absence of stable jockey Gerald Mosse through injury, Biancone had flown in another countryman, Eric Legrix, as a replacement. The absence of Charming Talker and the fact that the equally-brilliant Deerfield remains under a slight cloud, suggests that this year's Classic could go to an outsider. Biancone now is virtually certain to confirm a start for Tom's Charge in the richest domestic race on the calendar with Legrix to ride. Tom's Charge stormed home for third over 1,600 metres last time and the lightly-raced French import could easily run a good race in the 1,800-metre Blue Riband. Tom's Charge had been offered to Lester Piggott, but now the 57-year-old star could find himself without a ride in the big race. He had an alternative offer to partner Northern Celadon, second string for David Hill, but that horse may now not run. The English import worked disappointingly on Tuesday and Hill feels he will be a better horse next season. ''I have spoken to the owner and he has left the decision to me. I will be sleeping on it, but you would have to say a start is doubtful.'' Cruz, if fit, will ride Classic Trial winner Happy Guy for Brian Kan Ping-chee. The former champion trainer said at Happy Valley last night: ''Tony had confirmed he would ride Happy Guy. I think the horse will run very well. But now we will have to wait and see how Tony is, although I don't think it will be a problem. ''The horse has worked in good style since the Classic Trial and if he sees out the trip he could be hard to beat. ''My stable jockey, Felix Coetzee, will ride Right Way, my other runner.'' With Cruz confirmed for Happy Guy, Australian ace Darren Beadman will ride Northern Fire Ball for trainer Wong Tang-ping.
