Uruguayan players' union chiefs have called on FIFA to annul the nine-match international ban handed to striker Luis Suarez last year.
The 28-year-old was punished for biting Italy defender Giorgio Chiellini during a group game at last summer's World Cup finals in Brazil - his third such offence.
It is claimed by the union that their star player is a victim of widespread corruption deep within world football's governing body, and the issue will be raised at today's meeting of the FIFA Congress.
Suarez was not allowed to play for new club Barcelona until October after being suspended from all football activity for four months, while his international hiatus was set at nine matches.
That means that the former Liverpool man will miss this summer's Copa America in Chile, which gets underway on June 11.
Clarifying the situation, legal advisor for the Uruguayan body, Ernesto Liotti, is quoted by BBC Sport as saying: "With these facts [of alleged corruption], FIFA's decisions in the last few years have come under a mantle of suspicion.
"We have no proof that this [sanction] was made within the framework of illegal actions but nothing guarantees us that it wasn't."
It is claimed that, because the now-suspended Venezuelan Football Federation president Rafael Esquivel was on the FIFA disciplinary committee that passed down the hefty suspension to Suarez, it should be completely annulled at this stage.
