Jannik Sinner, the world’s top-ranked tennis player, has announced an early end to his 2026 season due to a knee injury. The Italian athlete shared the decision in a social media video on Tuesday, stating that he and his medical team agreed he requires treatment that will sideline him for the remainder of the year.

Sinner’s withdrawal comes just over a month before the ATP Finals in Turin, where he was scheduled to defend his title. The 25-year-old secured victories at the tournament in the previous two seasons, describing those wins as moments filled with “beautiful feelings and emotions.” He acknowledged that this year’s conclusion would be markedly different but emphasized the importance of focusing on his long-term health and career.

Despite grappling with injuries throughout the season, Sinner delivered a strong performance in 2026. He captured the Wimbledon championship in July and triumphed in five Masters 1,000 events, maintaining an undefeated record in six finals appearances this year. The decision to pause his competitive schedule aims to facilitate recovery and preserve his potential for future success.
