GENEVA (AP) ― A South Korean player who raised diplomatic tensions with Japan by displaying a political sign at the London Olympics after the countries’ bronze-medal soccer match was banned for two World Cup qualifying matches on Monday.

FIFA said Park Jong-woo was guilty of unsportsmanlike behavior that “cannot be tolerated,” and formally warned the Korea Football Association.

The International Olympic Committee can now decide if Park will get his medal, which has been withheld since the Aug. 10 incident.

After South Korea beat Japan 2-0 at Cardiff, Wales, Park displayed a sign in national colors with the slogan “Dokdo is our territory” to support sovereignty over islets that Japan also claims in a decades-old dispute. In defending Park, Korean officials argued that he simply picked up a banner that was thrown from the stands.

FIFA said its disciplinary panel “took into account that the behavior of the player, even though it appears not to have been premeditated or intentional, contradicts the principal idea and goal of sportsmanship and fair play, and therefore, cannot be tolerated.”
