Tennis world number one Jannik Sinner has been banned for three months over doping, Anadolu Agency reports citing the World Anti-Doping Agency (WADA).

"The World Anti-Doping Agency (WADA) confirms that it has entered into a case resolution agreement in the case of Italian tennis player Jannik Sinner, with the player accepting a three-month period of ineligibility for an anti-doping rule violation that led to him testing positive for clostebol, a prohibited substance, in March 2024," WADA said in a statement.

"WADA accepts that Mr. Sinner did not intend to cheat, and that his exposure to clostebol did not provide any performance-enhancing benefit and took place without his knowledge as the result of negligence of members of his entourage," it added.

Under the agreement, his period of ineligibility will run from Feb. 9 to May 4. This includes credit for four days previously served during his provisional suspension.

World No.1 will be eligible to return to official training activities starting from April 23 this year.

The 23-year-old Italian has won 19 singles titles, including three majors at the 2024 Australian Open, 2024 US Open, and 2025 Australian Open.
