ENGLISH jockey Willie Ryan has been targeted by Gary Ng Ting-keung to replace rejected Frankie Dettori as his stable's retained rider. Ryan, 28, currently rides for the top Newmarket-based handler Henry Cecil, generally partnering those horses not owned by the likes of Khalid Abdullah or Sheik Mohammed who personally retain Pat Eddery and Michael Roberts. Ng said yesterday: ''Willie is the most probable replacement for Frankie from a number of jockeys that I have been considering.'' Ng has been given an extension until June 7 to find a stable rider but it would be a major surprise if the Ryan deal was not completed within the next fortnight. Ryan, who in 1985 tied with Hongkong-bound Gary Carter for the British apprentice title, has already let Cecil know about his Hongkong prospects. He is expected to fly to the territory in the next week to 10 days to finalise details with Ng. Ryan has ridden here before, partnering 14 winners for Brian Kan Ping-chee during a prolific period six years ago. Unlike Dettori, Ryan is not expected to be refused by the Royal Hongkong Jockey Club's licensing committee. Philip Johnston, the Club's Director of Racing, said last night: ''Of course, any application from Gary (Ng) to retain Willie Ryan next season will have to be considered by the stewards. ''But there doesn't seem to be any reason why a jockey of his standing would not be entirely acceptable.'' Last season Ryan completed his first century, partnering 105 from 743 rides to finish seventh in the British jockey standings - one place and four winners ahead of Dettori. Meanwhile, champion trainer John Moore has taken retained jockey Darren Beadman off top Queen Mother's Cup hope Motivation on Saturday and informed the Australian ace that he can expect minimal stable support for the remainder of the season. Beadman makes his comeback to the saddle at Happy Valley tonight following his heavy fall from ill-fated Rainbow Connection a fortnight ago but his end-of-season has been soured by a letter received yesterday afternoon. ''I received a letter from John (Moore) today and he has given me a list of about nine horses to ride over the next couple of racing days. ''He suggests that I get other rides from trainers who have used me in the past as he will not be putting many my way in the remaining meetings this season. ''I am upset about Motivation and Jollity on Saturday because I was booked to ride those horses and could have had other rides in those races. I don't know what it's like here but it was a definite booking and I am intending to talk to Philip Johnston andBernard Hargreaves about that. ''John rang me on Monday night and we went through the rides and I marked them off. Then this afternoon I get a letter taking me off them and telling me that I will have very few rides from the stable. ''I am only to turn up for trackwork at 6 am if I want to,'' added Beadman. The rides on Champions and Chater Cup runner-up Motivation and facile last-start winner, Jollity, have gone to John Marshall, who will be Moore's stable jockey next season. Beadman returns tonight with rides on Simply Great and Prince Of Minstrel and said: ''I will be here until the end of the season, looking for as many rides as possible and as many winners.''
