Jannik Sinner withdraws from Cincinnati Open with right knee injury

Jannik Sinner has withdrawn from the Cincinnati Open in Mason, Ohio, on August 12, 2026, after the World No. 1 sustained a right knee injury. Tournament organisers and the ATP issued a short statement confirming the withdrawal.

Sinner said his knee had been bothering him for a while and that, despite working closely with his medical team, he “wasn’t yet fit enough to compete,” adding that he was “not ready to compete yet” and would shift his focus to getting right for New York, according to the statement released through the tournament and the ATP.

The withdrawal interrupts a season that has mixed high peaks and unexpected setbacks for the Italian. He arrived at the Australian Open chasing a third straight title there but lost to Novak Djokovic in a five-set semi-final, which ended his three-peat bid.

Following that defeat, Sinner won five consecutive Masters 1000 events — Indian Wells, Miami, Monte Carlo, Madrid and Rome — completing the Career Golden Masters and extending a win streak to 30 matches, according to the article.

He then suffered a second-round exit at the French Open against Juan Manuel Cerundolo, which ended a run of nine straight major finals, but recovered to defend his Wimbledon title with a victory over Alexander Zverev in the final.

Sinner has now skipped both the Montreal event and Cincinnati and, including the upcoming Cincinnati Open, has missed three tournaments: the Washington Open, Canadian Open and Cincinnati Open, the report states.

With Sinner and Carlos Alcaraz absent from the draw, the article says the ATP Masters field in Mason, Ohio, is thinner, leaving Novak Djokovic and Alexander Zverev as headline names alongside Taylor Fritz and Felix Auger-Aliassime.

Sinner was the 2025 Cincinnati runner-up and stood to defend 650 ranking points this week, which he will now lose; the Italian is expected to return directly at the upcoming 2026 US Open, starting from August 23.
