South Korea attacking midfielder Lee Jae-sung is a doubt for Friday's Asian Cup Group C match against Kyrgyzstan due to a toe injury, according to the Korea Football Association (KFA).
The 26-year-old, who played 86 minutes of the Korean's 1-0 win over the Philippines on Monday, did not take part in Wednesday's training session.
"Lee's right big toe was bent during South Korea's opening match against the Philippines on Monday, and he is feeling pain," a KFA official told the Yonhap News Agency.
"The swelling in his toe is getting better, but for quick recovery, Lee didn't take part in today's training. He's currently staying at a hotel for rehabilitation."
Portuguese coach Paulo Bento will also be without Ki Sung-yueng after the Newcastle United defensive midfielder injured his hamstring in Monday's game.
Ki, 29, has been ruled out for a week and will also miss second-placed Korea's final group game against leaders China on Jan. 16 when Son Heung-min is scheduled to make his tournament debut. (Reporting by Rohith Nair in Bengaluru)
