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.

Jannik Sinner's case was "a million miles away from doping", says World Anti-Doping Agency general counsel Ross Wenzel.

Tennis faces a new crisis of perception despite following its own rules on integrity. The two-tiered resentment is not going to fade away.

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.
