For the second time this season a top-tier team fielded an ineligible foreign player yesterday when Kitchee lost to Convoy Sun Hei in the League Cup semi-final at Mong Kok Stadium. With one minute to go, Kitchee, who were down 1-0, brought in expatriate Carlos Caceres to replace Landon Ling. The Chilean became Kitchee's seventh foreign player on the field, but the rules allow a maximum of six. In the end, with the score remaining at 1-0 to Sun Hei, it made no difference to the final outcome. Sun Hei will now meet TSW Pegasus in the final. Sun Hei lost to the district team in the Senior Shield earlier this season. Lau Chi-keung scored the only goal of the match in the 54th minute when he was free to head home a Chan Yiu-lun corner-kick from the near post. In October, Pegasus beat South China 3-2 in the league, but the Caroliners were awarded a 3-0 victory after Pegasus were found guilty of fielding seven foreign players at one time. Kitchee boss Ken Ng Kin said the blunder occurred in the final minute when they had to make a rush substitution due to Ling's injury. 'We had lost the match already and so the incident makes no difference,' he said. The Football Association will study the case in two weeks, according to general secretary Lam Shing-kui. Kitchee now face a fine of HK$10,000.
