Iraq have had a 2-0 Olympic qualifying win over the UAE taken away after fielding an ineligible player in their November 27 match in Doha, Asian officials said on Wednesday.
The UAE were awarded the three points and a 3-0 victory, the Asian Football Confederation (AFC) said.
Iraq defender Jasim Faisal should have been suspended for the Group B game, according to the AFC's disciplinary panel.
Faisal had been booked against Iran in the second round of qualifiers before he picked up another yellow card in the third round against Australia, earning him a suspension.
Iraq, who dropped to the foot of Group B, were also fined 7,000 Swiss Francs (around $7600).
