Hong Kong coach Chan Kong-wah faces severe sanctions from the game's governing body after manhandling the tournament referee at the World Championships in Paris. Chan, the three-time Commonwealth Games gold medallist, pushed and shoved Bernard Barbier of France after becoming incensed over a disputed call during a quarter-final involving doubles pair Cheung Yuk and Leung Chu-yan. The 43-year-old Chan had to be restrained by security staff at the Palais Omisports after Barbier waved a red card at him, then disqualified the players. The flashpoint came during the seventh and decisive game of a match which could have guaranteed Hong Kong their first ever men's World Championship medal. During a rally against South Korea's Kim Taek-soo and Oh Sang-eun, Leung raised his hand to indicate the ball had hit Oh's hand. The play continued until a Korean shot missed the table, but Hungarian umpire Robert Szentgyorgyi awarded the point against Hong Kong, making the score 7-5 in the Koreans' favour. 'He always makes mistakes,' an unrepentant Chan said of Szentgyorgyi. 'I've known him a long time. He creates so many conflicts. The umpire said he gave the point to Korea because we stopped the game. It wasn't stopped. Our players just raised their hands. I said, 'OK, play a let', but Korea weren't satisfied.' Chan's furious protestations earned him a red card from Barbier, who then disqualified the Hong Kong pair when it became apparent the Guangdong native was not going to let the match continue. 'I showed him a red card because he would not play on,' said the referee. 'After that, he became more aggressive and he touched and pushed me. I stopped the match. For me, they are disqualified.' The Hong Kong team launched an appeal challenging the interpretation of the scoring laws. An International Table Tennis Federation (ITTF) jury was due to meet this morning (Hong Kong time). However, there appeared to be little chance of the ruling being overturned. But Chan is likely to pay for his actions, thought to be unprecedented in the modern era. The fracas took the shine off what had been a significant achievement for the men's doubles partnerships, both reaching the last eight for what is believed to be the first time at a World Championship. While the row was brewing, Li Ching and Ko Lai-chak were threatening to defeat Chinese pair Ma Lin and Qin Zhijian, taking a 2-1 lead before going down 11-13, 11-8, 12-14, 11-3, 11-6, 11-5. Hong Kong's interest in the tournament ended yesterday with the defeats of Tie Yana and Lau Sui-fei in the last 16 of the women's singles. Both lost to Chinese opponents. Tie, whose ranking of number seven in the world makes her the most senior player, lost 6-11, 11-8, 11-4, 9-11, 11-7, 11-8 to Li Ju, the world number 11 from Jiangsu province. Lau, meanwhile, was beaten by the 1999 and 2001 world champion Wang Nan in four close games. In the men's singles, Leung Chu-yan mounted a heroic fight-back against Taiwan's Chiang Peng-lung, a player ranked 49 places above him, in the last 16. The 25-year-old earned four match points in a seesaw final game before falling 13-11, 11-8, 11-5, 4-11, 9-11, 9-11, 16-14. Li Ching also found himself on the brink of victory against South Korea's Joo Se-hyuk. Leading 3-2 and 10-7 in the sixth game, the 28-year-old Guangdong native lost the next two points before calling a time out. 'It was tactical,' he said. 'If it had worked it would have been a brilliant idea. It didn't and I lost.' Li lost 5-11, 11-5, 9-11, 12-10, 5-11, 14-12, 11-6.
