Australian firebrand Nick Kyrgios has once again taken aim at world number one Jannik Sinner over anti-doping testing in tennis before quickly deleting his social media post.
Kyrgios has been among the harshest critics of Sinner and world No. 2 Iga Swiatek after they failed drug tests last year.
Sinner tested positive twice for an anabolic steroid in March, but avoided a suspension because the International Tennis Integrity Agency (ITIA) determined he was not to blame.
Swiatek, a five-time Grand Slam winner, tested positive for a banned substance in an out-of-competition sample last August.
The world number two received a one-month suspension from the ITIA, which accepted that the test result was caused by contamination of her sleeping medication.
The sport was then rocked by a third doping saga when Australian Max Purcell went into a voluntary provisional suspension after admitting to violating the Tennis Anti-Doping Programme.
Australian tennis star Nick Kyrgios made another very public criticism of Jannik Sinner on Tuesday.

On Tuesday morning, Kyrgios announced on X that he had been chosen for a drug test, posting photos of the paperwork along with a sample of his urine.
“Ahhhh, I got a random drug test again today,” Kyrgios wrote.
'That's about four times in the last two months. Blood too. Absolutely useless, since even if the result is positive, you can play anyway.”
The controversial Australian decided to delete his post shortly after, but not before his followers gave their opinion on the matter.
“Nic, it looks like you need to hydrate a little more,” one fan joked, referring to the star's sample status.
“I really appreciate you posting a pic of your penis,” another sarcastically commented.
“Nick, in Italy we say get a life, you're always thinking about the redhead,” said a third, referring to Sinner.
Last month, Kyrgios called the doping scandals “disgusting” for tennis.
Tennis fans mocked Kyrgios after he posted a photo of his urine sample.

“Two world number ones convicted of doping is disgusting for our sport. It's a horrible sight,” Kyrgios said at his international press conference in Brisbane.
“The integrity of tennis right now and everyone knows it, but no one wants to talk about it, it's horrible.”
Kyrgios, 29, has struggled since June 2023 with wrist and knee injuries. He was asked about his motivations for speaking out about the Sinner and Swiatek situations.
“Someone like me… would never even try to dope me in this sport in my entire life,” he said.
“Especially going through an injury like I did, obviously there are things that could speed up the healing, help me get back to the main level, help my recovery.
“There are so many things that are prohibited in our sport that I could have done to recover faster… (but) that's not who I am.” I'm always against that.
“So when people say I'm disrespectful to the sport, I think someone like that who has tried to game the process, and hasn't really done it completely on their own merits, is the disrespectful one in my opinion.
'I have to be frank about it because I don't think there are enough people talking about it. “I think people are trying to sweep it under the rug.”

Sinner had successfully argued that his physiotherapist had accidentally contaminated him during treatment with clostebol, which had been transferred from a cut on his own hand.
Kyrgios raised questions about what happened next.
“I pay my team hundreds and thousands of dollars to be the professionals that they are and to make sure that doesn't happen,” Kyrgios said.
'So they knew what had happened. Why did they wait five to six months to do something about it? He kept his team for five months… that doesn't make sense.
'I would be furious. If my physical therapist contaminated me, put me in this situation, I would probably never talk to that guy again. He had him on his team for five months, acting as if nothing had happened.
Kyrgios has been criticized for his outspokenness but said he would not budge on issues he held dear.
“For a kid who grew up playing tennis, I enjoyed the competition, I enjoyed playing,” he said.
“I can get excited, I can throw a racket, but that's nothing compared to cheating and taking performance-enhancing drugs.” That's ridiculous in my opinion. Anyway, I'm not going to shut up.
