Jannik Sinner returns to action at the Italian Open after the conclusion of the World No 1’s three-month doping ban. Sinner has not played since winning the Australian Open in January for his third grand slam title after the Italian reached a resolution agreement with the World Anti-Doping Agency (WADA).

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

The settlement in the doping case was made in February, after WADA appealed a decision last year by the International Tennis Integrity Agency to fully exonerate Sinner for what it deemed to be an accidental contamination by a banned anabolic steroid in March, 2024.
