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.

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 World Anti-Doping Agency told the BBC that it rejected criticism of the settlement reached with the men’s World No 1

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?"
