South Korea may seek to revise its military exemption program for athletes amid calls for stricter rules after the country's soccer and baseball teams earned the exemption by winning gold medals at the Asian Games over the weekend.

Military service is a highly contentious issue in South Korea, where all able-bodied men must complete about 21 months of service as part of efforts to maintain a deterrent against the North.

Exemptions are offered to athletes who win titles at the Asian Games or medals of any color at the Olympics, however, and Tottenham Hotspur striker Son Heung-min along with his teammates earned that right when they struck gold Saturday.
