"We received the match reports and there was no reference to the wristbands," meaning there will be "no further action," FIFA said in an e-mailed statement Thursday.
FIFA last week asked the Iranian Federation to clarify media reports that several players were permanently banned for showing support for defeated presidential candidate Mir Hossein Mousavi.
It received a reply stating that "no disciplinary action has been imposed on any players of the Iran national team by any authority."
