Jannik Sinner Olympics

The Italian tennis sensation would have made his Olympic debut in Paris only for his condition to worsen despite medical treatment, causing doctors to advise him to prioritise his health and rest, ultimately leading to his withdrawal from the competition.
"Competing at the Olympic Games was one of my main goals for this season,” he stated in a heartfelt message. "I was really looking forward to representing my country and playing in this iconic tournament.”
Jannik Sinner Doping
Jannik Sinner was cleared of any wrongdoing on August 20, 2024, after failing two anti-doping tests due to contamination from his physiotherapist while treating a minor injury.

Regardless, Sinner was stripped of his ranking points, prize money, and results from the BNP Paribas Open at Indian Wells in March — as an in-competition test at that tournament on March 10, 2024, detected an adverse analytical finding (AAF) for clostebol the following month.
WADA appealed the decision in Sinner's doping case to the Court of Arbitration for Sport, seeking a suspension of one to two years for the player. The appeal was filed on September 28, 2024, and the hearing will take place in April 2025.
