Peru will now have to compete at the FIFA World Cup without their captain Paolo Guerrero after the star striker had his drug ban increased.
Guerrero had initially been handed a 12-month ban by FIFA for failing a drug test in October 2017, with the sentence later reduced to six months on appeal.
This meant Guerrero was allowed to return to play on 3 May, with Peru's national team naming the 34-year-old in their preliminary FIFA World Cup squad.

But while Guerrero was allowed to return to play, the World Anti-Doping Agency (WADA) had appealed FIFA's reduced sentence, taking the matter to the Court of Arbitration for Sport (CAS).
On Tuesday, CAS opted to extend Guerrero's ban to 14 months, meaning he will now miss the June/July tournament in Russia.
CAS found the Flamengo forward had registered cocaine in his system after ingested a tea containing the prohibited substance.
The court also stated the player had not intended to enhance his performance but "did bear some fault or negligence, even if it was not significant, and that he could have taken some measures to prevent him from committing the [anti-doping rule violation]".
The Peru Football Federation released a statement saying it “profoundly regrets the lengthening of the ban imposed on our player Paolo Guerrero who has always shown exemplary conduct.”
“We will without doubt miss Paolo in Russia but we are convinced that our team, with its courage and tenacity, will do Peru proud. No matter how tough the adversity, it will not stop our team.”
