Taking into account the circumstances of the case, the FIFA AC imposed a 6-month period of ineligibility on the Player, instead of the 1-year minimum suspension provided by the FIFA Anti-Doping Regulations, applicable in case of no significant fault or negligence.
Captain of the Peruvian national team Paolo Guerrero will be ineligible for this summer's FIFA World Cup in Russian Federation after having his ban for a doping violation partially upheld by the Court of Arbitration for Sport.
The Court of Arbitration for Sport has upheld an appeal by the World Anti-Doping Agency to extend Guerrero's six-month Federation Internationale de Football Association ban, which expired this month.
World footballers' union FIFPro has condemned the 14-month drugs ban that will rule Peru's captain and record goalscorer Paolo Guerrero out of the World Cup as "unfair and disproportionate".
Guerrero was subjected to an emotional roller-coaster after testing positive following the 0-0 draw in a qualifier away to Argentina in October. On Sunday he was named in his country's provisional squad preparing to play France, Denmark and Australia.
News of extension of the ban was not well received among Peru fans.
But WADA effectively retaliated, appealing to CAS to uphold their original sanction.
Guerrero, whose lawyers argued that the Benzoylecgonine was accidentally consumed in tea, plays his club football for Brazilian outfit Flamengo.
Both FIFA and the Court of Arbitration for Sport agreed Guerrero did not knowingly ingest the substance and that there was no performance-enhancing effect.
CAS said that Guerrero bore "some fault or negligence, even if it was not significant, and that he could have taken some measures to prevent him from committing an anti-doping violation".
In December, FIFA handed Guerrero a 12-month ban, ruling him out of the World Cup. The first one was being awarded a default win over their opponents, Bolivia, who were found guilty of fielding an ineligible player.
After the match, Guerrero said: "There is no reason for me to be suspended, I did nothing wrong and I trust the court to make the right decision".
