HONGKONG'S Simon Litster and Fijian giant Mesake Rasari needed more than three hours to provide urine samples for a random drug test yesterday. Litster was one of three Hongkong players picked at random to provide samples for tests conducted by the Scottish Sports Council prior to this week's World Cup Sevens. Hongkong players Stuart Krohn and Ashley Billington had no problems providing their samples but Litster, along with 1992 Hongkong Sevens player of the tournament Rasari, needed supervised time to produce the amount required for testing. Team manager Peter Burbidge-King who was asked by organisers to randomly select the three players, said: ''At noon we were asked to provide the samples within one hour. ''Those unable to provide them in that time were kept in a room under supervision until they could. ''Simon and Rasari were the only two who took three hours.'' Burbidge-King said the samples would be sent to London for analysis but the results not known until after the three-day tournament which starts this Friday at Murrayfield. It has been an eventful week for Litster who, at 37, has featured in the Scottish press as the oldest player in the tournament. A sales manager for Dunhill in Hongkong, Litster forced his way into the territory's squad for Scotland after a strong performance at the Hongkong Sevens last month. Litster, who will be 38 in two weeks' time, came into the Hongkong Sevens squad only after fellow forward Steve Burton pulled out through illness but he has managed to keep his place for Hongkong coach George Simpkin's 10-man World Cup squad which also includes Burton and Billington, who was missing from the Hongkong event. Simpkin is happy with the training since the squad arrived in Edinburgh on Sunday. Yesterday Hongkong trained with a group of local players at the Double Hedges training ground on the outskirts of Edinburgh. All the 24 teams taking part in the inaugural tournament have arrived in Edinburgh with the mighty Fijians making their presence felt - not so much visibly but definitely audibly. The Fijians, who involve religious rites in their physical and mental training, are accompanied by a priest for early-morning prayer sessions. Every morning at 5.45 they can be heard chanting from their priest's room. One official, who was staying in the room next door, said: ''They can even be heard from the street down below. Obviously they want to do very well here.'' Fiji have vowed to win the tournament after losing to Western Samoa in the final of the Hongkong Sevens. South Korea threatened to quit the tournament because the organisers used the wrong flag on publicity posters and souvenir shirts. The team found the flag of communist North Korea had been used instead of the Republic of Korea flag after they arrived in Edinburgh. Their first reaction was to turn round and go home but the players were talked into reconsidering by Scottish Rugby Union officials. ''We have registered a very strong protest,'' said a spokesman for the Korean embassy in London.
