Overview
- Djokovic became visibly unwell during his second‑round match at the Cincinnati Open, received a medical timeout after falling to his knees and appearing to vomit, and lost to Thiago Agustín Tirante in three sets.
- After the match Djokovic said he has dealt with an undisclosed health issue for many years and that it causes him significant problems in high heat and humidity.
- He received on‑court treatment including ice and medical checks, told reporters the episode was aggravated by nerves and match factors, and said he is unlikely to return to Cincinnati next year.
- The admission raises near‑term questions about his readiness for the US Open starting at the end of August because New York often has similar hot, humid conditions.
- The episode follows a more selective 2026 schedule for the 39‑year‑old and his recent exit from the PTPA, and it leaves two things to watch next: whether he or his team disclose a formal diagnosis and whether he changes his US Open entry or preparation plan.
