Many in the tennis world are expressing skepticism with the process that led to Sinner's three-month suspension

Novak Djokovic says the majority of tennis players have lost faith in tennis’ doping agencies after Jannik Sinner accepted a three-month ban, and that there are widespread feelings of “favoritism” for the sport’s biggest stars.

Australian Open champion Sinner, 23, received a sanction in August but was found by the International Tennis Integrity Agency (ITIA) to bear “no fault or negligence” after twice testing positive for clostebol — a banned anabolic steroid — at the Indian Wells Masters 1000 tournament in March. He was permitted to continue playing.
