South Korea defender Jang Hyun-Soo has received a lifetime ban from playing for the national team and hit with a $26,448 fine after he was found to have falsified records relating to his military service exemption.
All able-bodied South Korean men must complete almost two years military service as part of efforts to maintain a deterrent against the North but athletes can earn exemptions by winning a medal at the Olympics or gold at the Asian Games.
As part of the exemption conditions, athletes must undergo four weeks of basic military training and undertake more than 500 hours of community service over a three-year period.
Jang, who has 58 caps and was part of the team that won gold at the 2014 Asian Games in Incheon, had admitted to submitting false records detailing how many hours of community service he performed.
The Korea Football Association met on Thursday to decide how to punish the 27-year-old, who played in all three of Korea's games at the World Cup in Russia.
"Jang has been permanently disqualified from playing for the national team and has been fined 30 million won," a KFA spokesperson said on Thursday.
In addition to the KFA sanction, the Sports Ministry has given Jang an additional five days of compulsory service.
Suh Chang-hee, chairman of the KFA's disciplinary committee, said in a statement on their website that they decided it was not appropriate for Jang to continue to represent the country.
"The fine is a decision based on [Jang] damaging the reputation of the national team," Suh said, adding that there was no avenue for the player to have the ban lifted.
The KFA had taken such "severe disciplinary action to avoid similar cases in the future", he added.
Jang, who will now miss the Asian Cup in January, apologised on Thursday for failing to fulfil his basic military duties even after being given an exemption.
"I will humbly accept the KFA's punishment and the public criticism for being unable to live up to the public's expectations and the huge mistake I've made," he said in a statement on the KFA's website.
Tottenham Hotspur striker Son Heung-Min was the latest high-profile athlete to win an exemption after he led South Korea to the gold medal at the Asian Games in Jakarta in September.
