POPULAR winter visitor Walter Swinburn is poised to make a quick return trip to Hongkong to ride French challenger Urban Sea in the International Cup later this month. It will be handsome compensation for the dual English Derby-winning jockey whose one-month stint in January was cut short by a fall during trackwork at Sha Tin which put him in hospital where he was operated on for a punctured lung. He rode at only two meetings here but remained in Hongkong for most of the month recuperating before flying on to Dubai and back to England for the start of the present season. From his Newmarket home last night he said: ''It looks virtually certain that I will ride Urban Sea and I am very pleased. I have an agreement to do quite a lot of riding for the owner in France this season and that has led to the present situation. ''I hope there are no hitches as I am really looking forward to riding in Hongkong again,'' he added. Urban Sea is a Group Three winner and ran a top preliminary race in France two weeks ago. He is a definite challenge to River Verdon and hopes are high that hewill run well in the 1,800-metre showpiece. Swinburn, his Derby successes apart, is a noted big race rider and much in demand in Europe. His presence will add further interest to the International Races although he looks unlikely to have a ride in the Bowl. He will be available for other rides on April 18 and is expected to be legged up on at least three other mounts. Former Hongkong apprentice Mak Chi-wing has been suspended for three months by the Stipendiary Stewards of the Macau Jockey Club on a handling charge. Mak, formerly apprenticed to one-time Hongkong champion trainer Ng Chi-lam, was found guilty of failing to take all reasonableand permissible measures throughout the race to ensure that Double Jacket was given a full opportunity to win or to obtain the best possible place in Sunday's second event at Taipa. Mak's three-month ban starts after Thursday night's innovative Taipa meeting. The suspension hinged on evidence given by Double Jacket's trainer, ex-Hongkong amateur jockey George Williams. The Taipa stewards questioned both Williams and Mak about the running and riding of Double Jacket in the Class Five, 1,200-metre event and the trainer stated that he had instructed the jockey to attempt to have the mare in about fourth position but not to bustle her too much and to give her room in the home straight. Williams expected the mare to run on strongly but, after viewing the race and the patrol film, informed stewards that he was very disappointed with the ride as it appeared that Mak had made no effort to follow his instructions. Mak told stewards that he received interference shortly after the start and was then held up behind the field. The Stewards will also hold an inquiry on Thursday into the running and riding of Sunlight, trained by Terry K. Y. Tse and ridden by Alex Y. Y. Choy. The name of Sunlight was linked with controversy when trainer Leung Wing-ling was beaten up last month at Taipa. Sunlight finished unplaced in the seventh event on Sunday.
