Cavani banned for three matches over Jara incident in Copa America
But Cavani and the Uruguayan camp claimed he had been the victim of provocation which should have been spotted by the match officials.
Video footage appeared to show Jara attempting to goad the star by inserting a finger into his backside.
Jara was initially suspended for three matches, which was later reduced to a two-game ban on appeal.
But he still missed Chile's semi-final against Peru and the final victory 4-1 on penalties over Argentina.
Uruguay coach Oscar Tabarez has been handed a three-match touchline ban over the incident for insulting the referee.
