Jannik Sinner has accepted a three-month ban from tennis after the world number one admitted team mistakes led to him twice testing positive for traces of the banned substance clostebol in March last year.

The February 9 to May 4 suspension means Sinner will be free to play in the French Open, the second grand slam of the season, which begins on May 25 at Roland Garros.

In a statement, Sinner said that the World Anti-Doping Agency (Wada) accepted that he "had no intent and did not derive any competitive advantage from the two positive tests."

Australian Open champion Sinner has always said that clostebol entered his system when his physiotherapist used a spray containing it to treat a cut, then provided massage and sports therapy.

"This case had been hanging over me now for nearly a year and the process still had a long time to run with a decision maybe only at the end of the year," Sinner said.

"I have always accepted that I am responsible for my team and realise Wada's strict rules are an important protection for the sport I love. On that basis, I have accepted Wada's offer to resolve these proceedings on the basis of a 3-month sanction."

Wada said separately that "Sinner did not intend to cheat" but that he would serve his suspension as he is responsible for the actions of his entourage.

The agreement between Sinner and Wada means that Sinner will be able to play in front of his home fans at the Rome Open which kicks off just after the end of his suspension and is the last big clay court tournament before Roland Garros. (AFP)
