Slobodan Rajkovic will be allowed to play for FC Twente this season after FIFA partially upheld his appeal of a 12-month ban from football.
The 19-year-old, who is on a season-long loan from Chelsea, was banned in September after spitting at a referee during the Olympics.
He was initially banned from all football, but FIFA cut the ban to cover only international football at all age levels.
"The player Slobodan Rajkovic is suspended for 12 months starting from 3 September 2008, however this suspension only applies to all official and friendly matches of the player's representative team in all age categories," FIFA said in a statement.
"The player Slobodan Rajkovic is allowed to resume all activities at club level with immediate effect."
