South Korea have named Son Heung-min in their 26-man World Cup squad after the Tottenham forward declared himself fit for the tournament.
Son, 30, had been a doubt after having surgery on a fractured eye socket suffered earlier this month.
Coach Paulo Bento says he is not sure when Son can start training again, ahead of their first game against Uruguay on 24 November.
"We don't have that information yet," said Bento.
"We are in contact with him, with the Tottenham medical department. We need to wait, we need to analyse day by day his situation.
