Flamengo and Brazil striker Gabriel Barbosa, also known as ‘Gabigol’, had denied claims of attempted anti-doping fraud.
Presently, Gabigol has been suspended for two years for attempted anti-doping fraud.
Local media reports suggest that the 27-year-old made it difficult to undergo an anti-doping test the day before a game.
The Brazilian Doping Control Authority said: “The aforementioned athlete was judged by the Anti-Doping Sports Court of Justice and, by a majority vote, it was decided that a violation of the anti-doping rule of attempted fraud had occurred.”
But Barbosa, who has represented his country 18 times, denies the allegations.
“I have never attempted to obstruct or defraud any test, and I trust that I will be cleared by the higher court,” he said in a post on X.
“Since the beginning of my career as a footballer, I have always followed the rules of the game and never used banned substances. I have been subjected to dozens of tests, all of which have always been negative.
“I am disappointed with the outcome of the judgement, but I will continue co-operating with the sporting authorities and trust that my innocence will be proven and re-established by the higher court.”
The two-year ban for Gabriel Barbosa starts from the date of the violation, which occurred on 8 April 2023.
The Brazilian Serie A season begins on 14 April and concludes on 8 December, meaning Barbosa will miss the entire season but should be available for the start of the 2025 campaign.
Flamengo expressed surprise at the verdict and stated that they would assist the player with an appeal.
“(The club) will assist the athlete in presenting an appeal to CAS, since it understands that there was no fraud, not even an attempt, to justify the punishment applied,” they said in a statement.
Barbosa signed for Flamengo on a permanent deal in 2020 after a successful loan spell from Inter Milan, where he only played nine times in four years.
The forward scored the winning goal in the 2022 Copa Libertadores final – South America’s version of the Champions League – in a 1-0 win over fellow Brazilian side Athletico Paranaense.
Barbosa made his Brazil debut in a 2-0 friendly win over Panama in May 2016 and has scored five international goals.
