Sudan's Football Federation has appealed to the Court of Arbitration for Sport (CAS) to be re-awarded a World Cup qualifying victory they were stripped of.
Sudan had a 2-0 win over Zambia in Khartoum on June 2 taken away from them by FIFA for fielding an ineligible player.
FIFA awarded Zambia a 3-0 win by default after ruling that Saif Ali, who scored the second goal, should have been suspended for accumulating yellow cards in previous competitive matches.
The CAS aims to make its verdict regarding the appeal by the end of February, when the group matches get back under way.
As it stands, with Zambia being awarded the three points, they currently top the World Cup qualifying group courtesy of a 100% record from two matches, with Sudan on a single point.
