Nick Kyrgios aims thinly-veiled swipe at tennis stars who have breached doping rules after Aussie sensation suffers Brisbane International exit

Nick Kyrgios has spoken out again about doping in tennis, responding on social media to users who mocked his departure from the Brisbane International on Tuesday evening.

The Australian, 29, has spoken out about doping this year, particularly lashing out at Jannik Sinner, who failed two doping tests for clostebol in March.

Iga Swiatek was also handed a one-month ban for testing positive for a banned substance, while Max Purcell was also banned after admitting to breaching the sport’s anti-doping rules.

Ahead of the Brisbane International, Kyrgios called Sinner and Swiatek’s fouls ‘disgusting for our sport’, but the Australian has once again spoken out publicly on the issue, this time firing back at a social media user who mocked him.

It came after his defeat to Giovanni Mpetshi Perricard on Tuesday on his return to the ATP Tour.

Kyrgios suffered a 7-6 6-7 7-6 defeat in a close match, with his 21-year-old French opponent serving 36 aces during the match.

The Australian has made one competitive singles start on the ATP Tour in the last 18 months, with the Australian requiring wrist surgery after suffering a serious wrist injury.

While he was making waves on his return, a social media user mocked him.

“Nick Kyrgios gets 7-6 6-7 7-6-ed from the pitch by a server ten years younger than him,” the X user wrote, adding a clip from the film The Substance, in which a woman shows disdain for someone younger than her and more successful than her.

Kyrgios seemed to see the funny side at first, adding a “laughing face” emoji before writing: “Still haven’t passed drug tests though.”

Kyrgios also suffered a defeat in the men’s doubles at the Brisbane International alongside Novak Djokovic on Wednesday.

They were defeated 6-2, 3-6, 10-8 by Nikola Mektic and Michael Venus, painfully missing out on a place in the next round by two points in the final set tiebreak.

Despite this, the pair dazzled once again on the court and even danced together as they celebrated a point, while Kyrgios entertained fans at the Queensland Tennis Center by pulling off a tweener.

Kyrgios, meanwhile, claimed it would be a ‘miracle’ if he could play at the Australian Open this summer.

During his match against Perricard he seemed to suffer from some wrist problems after calling his physio to the court for treatment.

Although he has made some huge strides in coming back from the wrist injury, Kyrgios had admitted that the issue was still causing him problems.

“I felt like I’d been hit by a bus after doubles,” he said after admitting his pulse was “throbbing like a ****.”

“For my wrist, it’s all new territory…I went from practicing with unranked people to having the largest server…in the world and, ‘let’s see how you do.’

‘It’s going to be a tough day for my wrist tomorrow.

‘I was really looking forward to the Aus Open and after today… reality became fair.

“It (winning one) is perhaps one of the hardest things to do in any sport.

‘I almost need a miracle and the stars need to align so that my wrist can definitely hold up in a grand slam.

“But I’m so happy to be part of the Australian summer again.

“I don’t take it for granted; I’m going to go back there and play one of those top players… smiling to myself, knowing I’m right in the thick of the action.”
