The case of the world No. 1 in men's tennis is at the center of anti-doping protocols and reforms that could redefine its parameters.

The 23-year-old Italian will make his return to action at the Rome Masters 1000 in May, which will also serve him to test his condition ahead of Roland Garros. Having won the Australian Open at the beginning of the year, the ace from Sesto Pusteria can dream of completing the 'Calendar Grand Slam' already this year.

Jannik Sinner reluctantly agreed to a three-month suspension after “tricky” conversations with the World Anti-Doping Agency (WADA). The world No. 1, who lifted the Australian Open title last month, has been banned until May 4 after two positive drug tests in 2024.

The men's world No. 1 will miss several tournaments, but no Grand Slams. Here's what to know about the doping proceedings against him.

Jannik Sinner is getting used to a new reality after reaching an agreement with WADA, which will avoid him the hearing before the CAS in Lausanne but will force him to stay away from the ATP tour for three months.

Jannik Sinner received a 3-month ban after testing positive for a banned substance, with the Italian initially refusing to accept he would face a suspension.

Sinner asked: "Why would we do that if the first independent tribunal found it was no ban at all, why would I accept three months now?"
