Novak Djokovic’s Cincinnati Open Health Scare Raises Questions Before US Open

The 24-time Grand Slam champion had only returned to the Cincinnati Open last week, where he was beaten in dramatic fashion by Argentina’s Thiago Agustin Tirante after a physical battle. While the opening set of the match was easy for Djokovic, everything turned in the second when he started to feel it in the heat and humidity at age 39. He went to his hands and knees, needed medical help, seemed to vomit into a towel, and then lost 2-6, 6-4, 6-4.

The second-round match took place on Saturday, August 15, at the Lindner Family Tennis Center in Mason, Ohio. Djokovic was returning to Cincinnati for the first time since winning the title in 2023, and it was his first competitive match since Wimbledon in July.

What Happened to Djokovic During the Match?

Djokovic had controlled the match in the first set, winning 6-2. The tide turned in a brutal early second-set game. The third game went on for 18 minutes and had nine deuces, pushing Djokovic deeper into a physical battle, according to Reuters. Shortly after, he collapsed to the ground and was given treatment to lower his temperature.

Footage and photographs appeared to show how upset he was. He was sitting at the changeover with ice on his head and medical staff attending to him, and several outlets reported he appeared to vomit into a towel. The conditions were challenging, as Djokovic later pointed out, but he did not believe they were the sole culprit.

That is when the Novak Djokovic illness story really took over. Following the loss, Djokovic — who has struggled with a long-term health problem for years — said: “I have dealt with this for several years and it can (be an issue) in high temperature and humidity.” He went on to say hormones and nerves, as well as the stress of competition, can exacerbate the symptoms.

Djokovic Has Not Publicly Named a Diagnosis

Importantly, Djokovic did not disclose a concrete medical diagnosis. While he described the illness or condition as something that had a long history, he did not identify it. As a result, claims attempting to diagnose him from watching match footage go further than what has been validated in public.

The health condition of Novak Djokovic must be described carefully. Djokovic did confirm that claim, stating the issue has bothered him for the past two years, is aggravated by humidity and heat, and was behind his loss to Tirante. Unless either Djokovic or his medical team provides greater detail, anything more specific would be guesswork.

Tirante Earns the Biggest Win of His Career

The story of this match was all about the physical issues Djokovic had, but Tirante still had to see it through to finish off the upset. The 25-year-old Argentine bounced back from losing the first set and kept his cool as things got tougher for his opponent. With the final set tied at 4-4, Djokovic hit some untimely errors as Tirante claimed the critical break and held his serve to finish off the match.

Tirante’s result was deemed the biggest upset of his career by the Cincinnati Open. He had already downed Taylor Fritz in Montreal the week prior, but beating Djokovic at a Masters 1000 event was clearly a different level of achievement for the world No. 50. Tirante also chalked it up to his experience dealing with the nerves of playing a legend like Nadal.

Could This Be Djokovic’s Final Cincinnati Appearance?

The loss also cast doubt on the Serbian’s future in this tournament. The three-time Cincinnati champion, who had won the event in 2018 and then again in 2020 and 2023, said it now looked more likely than not that he would not be back next year but stopped short of making a final call.

ATP Tour has Djokovic rated 45–13 at the Cincinnati event, but it is worth noting that he went into the 2026 edition with a ten-match winning run there. His comments imply that the summer heat of Ohio might play a role in how often he competes next year.

What Does It Mean Before the US Open?

The focus is now on his recovery, with eyes turned towards the US Open. Cincinnati was the first match of the season on hard court for Djokovic, who fell in the semifinals at Wimbledon against Jannik Sinner, according to Reuters, and therefore it represents an important moment ahead of the next Grand Slam.

Of course, the Novak Djokovic issue looms, though one tough match against a top-very-bottom competitor does not automatically mean he’s out of action for a full major. While increasingly approaching the final phase of his career solely with the Grand Slams in mind, Djokovic gets through demanding times by working carefully on his condition between events.

Regardless, the Cincinnati episode was more than just a typical first-week loss. Because a health condition has troubled Novak Djokovic for years, it may rightfully be part of the wider conversation. As for a summary of what has been made available thus far, Djokovic appeared to have suffered a debilitating physical battle in Cincy, his ongoing problem was exacerbated by the hot and humid conditions, and the incident presents another question as he prepares for an upcoming major test.
