Lionel Messi is free to represent Argentina in their World Cup qualifiers after his four-match international ban was overturned by Larry Mussenden and his FIFA Appeals Committee.
The 29-year-old Barcelona forward was suspended for directing "insulting words" at an assistant referee during a 1-0 win over Chile in March.
He missed one match - Argentina's 2-0 World Cup qualifying loss to Bolivia.
A FIFA Appeal Committee spokesperson said while his behavior was "reproachable", the evidence was not sufficient.
He will now be available for matches against Uruguay, Venezuela and Peru as Argentina fight to secure a place at next summer's World Cup finals in Russia.
A fine of was also lifted.
During the Chile game, Messi was caught on camera venting his anger at an assistant who signaled he had committed a foul.
He was not shown a card at the time.
The FIFA Appeals Committee concluded "the evidence available was not sufficient to establish" an infringement had occurred.
"The appeal committee nevertheless underlines the importance of always showing respect to the match officials, stressing that such a principle is essential in football and any unsporting conduct that may be contrary to the principles of fair play cannot be accepted," it said in a statement.
