Swansea City midfielder Ki Sung-yueng is set to miss the start of the Premier League season due to a knee injury.
Ki sustained the problem in South Korea's 3-2 defeat in a World Cup qualifying match against Qatar last month.
Swansea have confirmed that the 28-year-old has undergone a minor operation in Korea which will likely rule him out of the pre-season schedule and the start of the league campaign.
However, Swansea are not expecting his injury absence to be a long-term issue.
"The club's medical team have been out to South Korea to assess him following the operation," read the club's statement on Monday.
"Although no date has been set yet for his return to action, the injury is not expected to keep him out long-term."
Ki made 23 Premier League appearances for Swansea last season.
The update on Ki comes after Fernando Llorente suffered a broken arm while cycling on holiday, although the striker is hopeful of returning in time for their opening-day match against Southampton.
