The Iranian soccer federation has denied reports that national team players were punished for wearing green wristbands in apparent solidarity with the political opposition during a World Cup qualifier last week.

Soccer's world governing body said Friday it received a letter rom the Iranian federation "which stated that no disciplinary action has been imposed on any players of the Iran national team by any authority."

FIFA had written to Iran on Wednesday asking for clarification on media reports that several players were permanently banned for showing support for defeated presidential candidate Mir Hossein Mousavi.

Players wore the wristbands during Iran's World Cup qualifier June 17 at South Korea.   

One player, Ali Karimi, had green bands wrapped around both wrists. Captain Mehdi Mahdavikia kept his band on even during the second half.
