The Argentina FA has been warned by Fifa that plans to rename their domestic league may breach rules on political involvement in football.
They plan to rename their top flight the Crucero General Belgrano First Division, after the cruiser which sunk during the Falklands War.
Fifa has now written to the Argentina FA for clarification.
"A potential change of name could be sanctioned in accordance with the Fifa Statutes," said a statement.
"Fifa has requested the AFA to provide further information on this matter and reminded the AFA of Article 3 of the Fifa Statutes which prohibits any kind of discrimination against a country, private person or group of people on account of ethnic origin, gender, language, religion, politics or any other reason."
The General Belgrano was sunk by a Royal Navy submarine with the loss of 323 Argentine lives in 1982.
