FIFA has lifted a four-match international suspension on Argentina forward Lionel Messi, world soccer’s ruling body said yesterday, in a significant boost to his team’s faltering World Cup qualifying campaign.

Messi, 29, was banned for insulting an assistant referee during a qualifier against Chile in March, a decision based on television images as the incident was missed by match officials.

Messi has already served one match of the ban, missing Argentina’s 2-0 defeat in Bolivia, and would also have sat out games away to Uruguay and home to Venezuela and Peru.

The suspension had been imposed by FIFA’s disciplinary committee only hours before kickoff of the game in La Paz. Argentina coach Edgardo Bauza was fired following the defeat.

FIFA’s appeal committee described Messi’s behaviour as “reproachable”.

However, it said that the “evidence available was not sufficient, according to the standards required....in sanctioning serious incidents which have been missed by match officials.

The appeal committee nevertheless underlines the importance of always showing respect to the match officials.
