Jannik Sinner to Miss Remainder of Season Due to Knee Injury

World number one Jannik Sinner has confirmed that he will not return to competitive tennis for the remainder of the season due to an ongoing right knee injury. The Italian star, who has not played since defending his Wimbledon title in July, made the announcement via an Instagram video.

Sinner, 25, stated that he needed to prioritise his long-term career, saying, “Me together with the doctors have decided that I need a course of treatment for my knee.” He reflected on the past few years, expressing gratitude for the emotions and experiences he has had, while acknowledging that this year will be markedly different.

Throughout 2026, Sinner was a dominant force on the ATP tour, achieving an impressive record of 44 wins against just three losses. He notably secured five consecutive Masters 1000 titles from March to May, becoming the youngest player to complete the ‘career Golden Masters’.

With Sinner sidelined, Alexander Zverev is poised to take over the world number one ranking by the end of the year. Zverev, currently ranked second, trails Sinner by 1,280 points in the live rankings but stands to gain significantly as Sinner will be unable to defend points from his title victories in China, Vienna, Paris, and the ATP Finals from the previous year.

In 2026, Sinner captured six titles across all surfaces and only lost one singles match between March and July. He reached the semi-finals of the Australian Open, where he lost a five-set thriller to Novak Djokovic, and faced an unexpected second-round exit at the French Open against Juan Manuel Cerundolo, which ended his remarkable 30-match winning streak.

Despite the challenges, Sinner showcased resilience at Wimbledon, where he overcame a tough first-round match and ultimately triumphed over Zverev in the final to defend his title. His rivalry with Carlos Alcaraz, which saw them meet in three Grand Slam finals last year, saw them face off only once in 2026, with Sinner winning the Monte Carlo Masters final to reclaim the top ranking.

As Sinner concludes the year with a 10-1 record against top-10 players, his focus now shifts to recovery and returning to the sport at full strength.
