Reuters reports WADA had appealed to the Court of Arbitration for Sport (CAS) against an independent tribunal's decision in August to clear Sinner of wrongdoing after the three-times major winner failed drug tests.

Sinner, who successfully defended his Australian Open crown last month, had tested positive for anabolic agent clostebol which the 23-year-old said had entered his system from a member of his support team through massages and sports therapy.

Sinner's ban began on February 9 and will end on May 4 while he can return to training on April 13. The French Open main draw is scheduled to begin on May 25.

"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," WADA said in a statement on Saturday.

"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.

"However, under the Code and by virtue of CAS precedent, an athlete bears responsibility for the entourage's negligence."

The case was set to be heard by CAS in April and Sinner was in danger of being banned for up to two years.

The Masters tournaments Sinner will miss include Indian Wells, the Miami Open, Monte Carlo and Madrid.
