Six Iranian footballers wore green wristbands in the match against Korea Republic in support for defeated presidential candidate Mir Hossein Mousavi.
The group of players, which included captain Mehdi Mahdavikia, donned the colours in support of Mousavi's election campaign.
Last week's election in Iran has bought about many protesters but critics have labeled the footballers antics as very defiant.
"They are going to be on a flight back to Tehran soon and they are going to be met at the airport possibly by people from the government," said the BBC's correspondent in the nation's capital, Jon Leyne.
"It shows you the defiance there is in the population here. It's one thing to go out on the street anonymous.
"It's another thing to show it to the world and of course the game was being shown live on Iranian state TV."
