Kitchee youngster Lo Chi-hin was recovering in hospital last night after collapsing during his side's AFC Cup group E match against Armed Forces of Singapore at Mong Kok Stadium. Substitute Lo, 18, only entered the match in the 79th minute but fell to the ground unconscious shortly after. The reason for his collapse was not clear. Kitchee lost 2-0. In group D, South China were beaten 4-1 by Home United in Singapore. Meanwhile, Hong Kong international Chan Siu-ki of Kitchee has been banned by his club for the rest of the season for his part in a training-ground brawl with goalkeeper Wang Zhenpeng.
