The Argentine Football Association has failed with their appeal to CONMEBOL regarding Lionel Messi's three-month ban following last summer's Copa America.
Messi was banned for three months from international matches and fined $50,000 in August after accusing South America's governing body for football of "corruption".

The Barcelona forward criticised the officiating and members of CONMEBOL following Argentina's semifinal loss to Brazil and after the third-place match against Chile but he later apologised.
Messi, 32, avoided the Copa America medal ceremony in protest and later said Argentina "shouldn't take part in this corruption."
Asked if he feared being suspended for his comments, he said: "The truth needed to be told."
Argentina sought to get Messi's ban reduced but failed. The ruling means he cannot return to international play until Nov. 3 and will therefore miss his country's friendlies against Germany and Ecuador.
Argentina face Germany on Oct. 9 and then Ecuador on Oct. 13.
