Uruguay's players' union has called on the Football Association to overturn Edinson Cavani's three-match ban.
The Manchester United striker was fined £1,000 and banned for an Instagram post containing a Spanish word that is offensive in some contexts.
Luis Suarez and Diego Godin have both shared a statement by their national players' union that calls the punishment a "discriminatory" act.
Uruguay's Football Association (AUF) also wants the ban reviewed.
Godin, Uruguay's captain, and striker Suarez shared on Twitter a letter of support for their international team-mate Cavani, written by the Uruguayan Football Players' Association (AFU).
