Kwon started as a forward in Dijon's French Ligue 1 match against Angers at Stade Gaston-Gerard in Dijon, France, on Saturday, but he was forced to leave the pitch in the 76th minute due to injury.

Although Kwon's exact injury status has not been revealed, he appeared to have a ruptured Achilles tendon and will likely be sidelined for months, according to French media.

Kwon, 23, is considered a key attacking player for South Korea due to his impressive season in France. The former Suwon Samsung Bluewings player, who joined Dijon in January 2017, scored 11 goals in 34 matches in France this season. With South Korea, Kwon has four goals in 16 appearances.

Kwon's injury will deepen concerns for South Korean head coach Shin Tae-yong. Shin's side had already lost center back Kim Min-jae and midfielder Yeom Ki-hun, while left back Kim Jin-su is doubtful for upcoming matches due to injuries.

South Korea will confirm their final roster of 23 players after they play two friendly matches at home next week. South Korea will face Honduras on Monday and take on Bosnia and Herzegovina on June 1.

At the World Cup in Russia, South Korea will face Sweden, Mexico and Germany in Group F. South Korea's first match against Sweden is scheduled for June 18 in Nizhny Novgorod. (Yonhap)
