Rio 2016 super-heavyweight champion Tony Yoka has received a suspended one-year ban after missing four doping tests.
The 25-year-old turned professional shortly after clinching Olympic gold two years ago.
All four unannounced tests were carried out during the period from July 2016 and July 2017.
Yoka’s lawyer Arnaud Pericard told AFP that the boxer had missed the first test whilst returning from training in the USA.
According to Pericard, the second missed test came during a “period of relaxation” when Yoka failed to realise he was “subject to geolocation requirements”.
The last two apparently were blanked when the boxer was in the US and not present at his home in France.
All four tests were administered by the French Boxing Federation’s (FFB) anti-doping controllers.
Three missed tests in a period of 12 months constitute a violation of anti-doping rules.
In a statement, the FFB said that it “obviously condemns all forms of doping or behaviour contrary to the ethics and values of the sport which it defends.”
Yoka has won his first three professional fights since becoming the first Frenchman to win the Olympic super-heavyweight title.
His next bout is against former French heavyweight champion Cyril Leonet in Paris on April 7th.
Yoka has also been signed up as a sparring partner by New Zealand’s WBO heavyweight champion, Joseph Parker.
The Kiwi is preparing for his unification title fight with London 2012 gold medallist Anthony Joshua.
To complete the Olympic connections, Yoka beat Parker to win gold at the Youth Olympic Games in Singapore 2010.
The Frenchman is married to Estelle Mossely, who captured gold in the women’s lightweight category at Rio 2016.
The pair have a son named Ali, born in August 2017.
