The former Arsenal star was hit by a one-year ban from FIFA after allegedly failing to pay money owed to a former agent.
Eboue has been banned from all football for a year by FIFA following a long-standing dispute with former representative Sebastien Boisseau, which stretches back to 2013.
The Ivorian was initially fined 30,000 Swiss Francs and given a 120-day period to pay the outstanding debt in September 2014, only to take the case to the Court of Arbitration for Sport.
However, that appeal was rejected, with Boisseau then requesting the imposition of a one-year ban.
FIFA has now granted that request, meaning Eboue will be unable to participate in any footballing activity for 12 months unless the outstanding debt is paid.
According to the Northern Echo, the exact amount owed by the defender is unknown.
A statement released by FIFA said: “Emmanuel Eboue, who has represented Côte d’Ivoire and is currently registered for the English club Sunderland AFC, is to serve a ban on taking part in any football-related activity that will last for one year or until he pays the total outstanding amount owed to his former agent if this occurs before the one-year ban has elapsed."
Sunderland have since responded to news with a short statement on their official website, stating they were unaware of the situation surrounding the 32-year-old and that they intend to terminate his contract as a result.
"Eboue signed a contract with Sunderland AFC until the end of the current season and the club has therefore given notice of its intention to terminate the contract. The player has two weeks in which to appeal this decision."
It means the former Arsenal star, who signed as a free agent earlier this month following his release by Galatasaray in the summer, would leave the Black Cats without making a single appearance for the club.
