Former Australian tennis player Marinko Matosevic has been banned from the sport for four years after a serious doping case. The decision was confirmed by the International Tennis Integrity Agency. The ruling means he cannot play, coach, or be part of any official tennis event until March 2030. He has also been asked to return prize money from tournaments linked to the case.The 40-year-old, who once reached world No 39 and was Australia’s top-ranked player, had already retired in 2018. But the case focused on actions between 2018 and 2020. An independent tribunal reviewed the matter and found multiple violations. The story has now raised fresh questions around integrity in tennis and how strict the system is.
Marinko Matosevic doping case details as ITIA confirms four year ban and tribunal rejects his claims
According to the International Tennis Integrity Agency, Marinko Matosevic was involved in five anti-doping breaches. These included using a banned method linked to blood doping while still an active player. He was also found to have helped another player dope, shared advice on avoiding tests, and used and possessed a banned substance called clenbuterol.Because of this, his results from two tournaments in 2018 have been removed. He must also return the prize money from those events, which is reported to be around £3,000, as per Perfect Tennis.Matosevic was officially charged in May 2025. At first, he denied all the allegations. Later, he admitted to blood doping in a social media post. In that message, he also strongly criticised the process.He wrote, “I am writing this confession letter firstly to warn other athletes against doing anything that may harm their health and put their lives at risk.” He added, “Secondly, I am writing this letter to let the tennis world know how corrupt and unjust the ITIA process is.”He further claimed, “They take your phone number under threatening circumstances and make legal cases over photos and text message assumptions that are literally five years old. The whole process is corrupt and lacks credibility, as we have seen over the last few years!”However, the tribunal did not agree with his claims. The panel said the International Tennis Integrity Agency followed proper rules under the Tennis Anti-Doping Programme. Tribunal chair Michael Heron KC said Matosevic’s actions were serious and intentional.He stated, “His conduct strikes at the integrity of the anti-doping framework.”Matosevic’s ban will remain in place until March 15, 2030, as long as the prize money is repaid. Until then, he is not allowed to take part in any tennis activity linked to major governing bodies.Born in Bosnia and Herzegovina, Matosevic turned professional in 2003. His best Grand Slam results came in 2014, when he reached the second round at Wimbledon and the French Open.
