Nick Kyrgios said the recent doping incidents involving Jannik Sinner and Iga Swiatek were "disgusting" for the sport, as the Australian slammed authorities on Saturday over what he saw as lenient treatment in their cases.

Nick Kyrgios slammed the Jannik Sinner and Iga Swiatek doping cases as "disgusting" and "horrible" ahead of his ATP comeback. Anyone who has been regularly following tennis for the past couple of months, knows extremely well that the 2022 Wimbledon finalist has been very sharp in his criticism of the two high-profile doping cases.

Nick Kyrgios continues to add to his digs of World No.1 Jannik Sinner reposting a mocked up Christmas image of the pair and adding his own comment. Kyrgios has long been at the throat of Sinner over his positive test for substance Clostebol in which he escaped suspension twice.

Nick Kyrgios has launched a savage attack on tennis stars Jannik Sinner and Iga Swiatek for breaches of the sport's anti-doping program, labelling their conduct as "disgusting for our sport".

World number two Iga Swiatek has admitted she feared the reaction to her positive doping test earlier this year - before boldly declaring 'there are going to be some negative comments.'

Jannik Sinner faced no ban in the verdict given by the International Tennis Integrity Agency (ITIA) after testing positive for the banned anabolic steroid clostebol.

Iga Swiatek spoke for the first time on her one-month doping ban and the probability of a Jannik Sinner-type WADA appeal.

It was the second high-profile doping case to hit the sport in a matter of months following men's world number one Jannik Sinner 's two failed tests, for which he did not receive a ban.
