Houdet (51), had been a part of the athlete monitoring programme since January 2009. He was suspended for 15 month after failing to comply with doping control orders three times in 2021.
On appeal, the French champion challenged the validity of two of three failed tests. However, during a hearing on June 14, before an independent tribunal he failed to convince judges that he was not "negligent" in this matter.
His suspension will continue until March 26, 2021. His results, earnings, and points in tournaments between December 27, 2021 and June 30, 2022 will also be canceled. Houdet played after his appeal.
Stephane Houdet is the Triple Paralympic doubles champ in Beijing, Rio, and Tokyo. He has won 23 Grand Slam singles tournaments including Roland-Garros twice (2012) and the US Open twice (2013).
