South Korea is taking on Turkey in a third place play-off match Saturday. But it's uncertain whether three key players will be able to join the game. Both defender Choi Jin-cheol, midfielder Kim Nam-il who suffered ankle injuries, and forward Hwang Sun-hong sat out practice in Gyeongju on Thursday. Coach Guus Hiddink said it is a big setback. Analysts speculate that Hiddink may add new players to the starting line-up.
