Barcelona striker Luis Suarez's four-month worldwide ban has been upheld after an appeal to the Court for Arbitration for Sport (CAS) was rejected but he will be able to train with the club, according to the Associated Press.

Suarez, 27, was suspended from "all football-related activity" for four months by FIFA in June after he bit Italy defender Giorgio Chiellini while playing for Uruguay in a World Cup match.

An appeal against the ban was rejected by the world football governing body in July, before Suarez, Barcelona and Uruguay's football association (AUF) took their case to CAS. The former Liverpool striker attended the latest appeal hearing in Lausanne, Switzerland, last Friday as lawyers put forward his case.

But issuing judgement on Thursday, according to Associated Press, CAS ruled that the ban should remain in place but he will be able to train with Barcelona immediately.

CAS says FIFA's sanctions against Suarez are "generally proportionate to the offence committed." However, the court's panel has ruled that the ban on any football-related activity is "excessive."

The first match in which he will be eligible to play for the club could be el clasico, the league meeting with Real Madrid at the Bernabeu, if the match is set for Sunday, Oct. 26, when the Spanish league announces that weekend's schedule.
