Jannik Sinner has accepted a ban which expires in time for him to compete in the Italian and French Opens in May - triggering a "favouritism" accusation from Novak Djokovic.

Novak Djokovic says a majority of tennis players have lost faith in the anti-doping authorities following Jannik Sinner’s three-month ban, and there’s a widespread feeling that “favoritism” is being shown to 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.
