Sunderland are set to terminate the contract of defender Emmanuel Eboue after he was suspended by Fifa from all football-related activity for one year.
The 32-year-old, who joined the Black Cats until the end of the season on 9 March, was given the ban after failing to pay money owed to a former agent.
Sunderland said Eboue did not make the club aware of the matter, which relates to a dispute from July 2013.
The Ivory Coast international has two weeks to appeal against the decision.
Eboue, who has not made a first team appearance for the Black Cats, had been ordered by Fifa to pay agent Sebastien Boisseau an undisclosed amount he was entitled to under the terms of an agreement between the pair.
The former Arsenal full-back was fined 30,000 Swiss francs (£21,000) in September 2014 and given four months to settle the matter.
Eboue spent eight seasons at the Gunners after arriving from Belgian side Beveren in 2004, before moving to Turkey, where he won three Super Lig titles and five domestic trophies with Galatasaray.
He began training with Sunderland in February.
