Rwanda international Dady Birori has been banned from football for two years by the Confederation of African Football for holding two registrations with different details.
As well as a Rwandan passport, Birori also has a DR Congo passport under the name of Etekiama Agiti Tady, with different dates of birth on each.
Birori plays for AS Vita Club using his DR Congo passport and the name Tady.
His suspension is a huge blow for the player and his club, who have a two-legged Champions League semi-final against CS Sfaxien later this month.
In August Caf suspended Birori until further notice and disqualified Rwanda from the 2015 Africa Cup Nations qualifiers for fielding an ineligible player.
That initial ruling followed a protest made by the Congo Brazzaville Football Federation after Birori featured in the first leg of the second round qualifier between the nations last month in Pointe-Noir.
Rwanda had beaten Congo on penalties over two legs to reach the group phase but it instead the beaten side progressed to Group A of qualifying for the next year's finals in Morocco.
Congo have since gone on to win their opening two matches - including a 3-2 victory away to defending champions Nigeria - and are top of the table.
Although Rwanda had maintained that to their knowledge that the player had one identity, they lost an appeal against their disqualification.
Caf ruled that "the Rwandan federation was aware of this double identity but proceeded to feature the player for the national team while he held a different identity with the club".
