The Uruguay Football Association have hit back at FIFA vice-president Jim Boyce for accusing Liverpool striker Luis Suarez of 'cheating'.
The 25-year-old, who won the Copa America with Uruguay last year, was criticised by the FIFA chief after appearing to dive during the Reds' goalless draw against Stoke City at Anfield last weekend.
The Uruguayan governing body said in a letter: "The Uruguay Football Association has become aware of statements made by the vice-president of FIFA, Mr Jim Boyce. These expressions refer to the Uruguayan player Luis Suarez, calling his conduct an act of 'cheating' and that such a situation is a 'cancer' for football.
"We understand that this kind of comment coming from a person who holds the position of vice-president of FIFA, with specific reference to a football player and linking their actions to a disease that is a scourge on humanity, are at odds with the principles governing world football.
"Deliberately ignoring his position and role Mr Boyce has referred specifically to a football player, encouraging and provoking hostility towards them."
Meanwhile, Suarez has claimed that he needs to improve his conduct on the pitch.
