The men's world No. 1 could face a two-year ban. Here's what to know about the doping proceedings against him so far

Jannik Sinner has revealed he’s had “sleepless nights” amid his ongoing anti-doping controversy. The World No 1 said that he is “very disappointed and also surprised” after the World Anti-Doping Agency (Wada) announced that it would be appealing the decision to clear the Italian of a doping offence.

Novak Djokovic has given his reaction to the World Anti-Doping Agency’s decision to appeal the “no fault or negligence” verdict reached over Jannik Sinner’s failed drug tests. The International Tennis Integrity Agency (ITIA) announced last month that Sinner would not receive a ban for failing two anti-doping in March after an independent tribunal ruled he was not to blame.

World number one Jannik Sinner said on Monday that he was in "a very difficult moment" and enduring sleepless nights over his doping case.
