Nick Kyrgios says he didn't know that Novak Djokovic was allegedly poisoned in Australia three years ago but the 29-year-old backed the Serb's claims by stating that Australia treated him in a very bad way.

Nick Kyrgios has reiterated his support of Novak Djokovic in light of the 24-time grand slam champion's recent claims he was "poisoned" while in hotel quarantine.

Kyrgios, who revealed after his singles comeback on Tuesday that he is still struggling with pain in the wrist that has kept him out for 18 months, produced two through-the-legs shots in one memorable rally, and he and Djokovic looked poised for victory at 8-6 ahead in the deciding tie-break.

After all the talk and bluster, Nick Kyrgios finally returned to the court for a professional tennis match. Kyrgios missed the better part of two years due to injuries and returned in style alongside Novak Djokovic for a highly publicized doubles match.

Nick Kyrgios made his long-awaited return to tennis at the Brisbane International earlier this week, where he is teaming up with Novak Djokovic.

Nick Kyrgios appreciated very much Novak Djokovic siding with him and highlighting that some of the Australian's comments about the Jannik Sinner doping case make sense. The 29-year-old's criticism of the handling of the Italian's case is well-documented and there is no need to say much about that.
