World number one Jannik Sinner announced on Tuesday, October 6, 2026, that he is officially ending his 2026 tennis season due to a persistent right knee injury. The 25-year-old Italian player has been sidelined from the ATP circuit since capturing his second career Wimbledon title in mid-July. According to reports from the Italian press cited by Agence France-Presse (AFP), Sinner is dealing with a tendinopathy in his right knee alongside inflammation surrounding the iliotibial band.
Sinner Ends 2026 Season to Treat Knee Inflammation
In a video statement published to his social media channels on October 6, Sinner addressed his supporters directly. “I wanted to give you some news,” Sinner said. “With the doctors, we decided that I had to undergo treatment for my knee. This means that my 2026 season is officially over.” An accompanying statement ruled out any surgical intervention, confirming that the player will manage the inflammatory condition through treatment.
The early shutdown carries immediate consequences for the end of the tennis calendar. Sinner will miss the ATP Finals, scheduled to take place in Turin in November. He won the previous edition by defeating Spain’s Carlos Alcaraz 7-6 (4), 7-5. His 2026 campaign featured triumphs at Masters 1000 titles in Indian Wells, Miami, Monte-Carlo, Madrid, and Rome, alongside his Wimbledon crown.
Rankings Implications and the Race for Number One
Sinner’s withdrawal threatens his hold on the summit of men’s professional tennis. AFP notes that the extended absence will cost the Italian a significant tally of ranking points, given that he had titles at Vienna, the Paris Masters, and the Turin ATP Finals from the prior season. Holding 11,000 points currently, Sinner’s lead at the top has shrunk to 1,280 points over Germany’s Alexander Zverev.
Zverev enters the final stretch of the season on the heels of a career-best run. The 29-year-old German secured two Grand Slam titles in 2026 by winning Roland-Garros and the US Open, complemented by a semi-final finish at the Australian Open and a runner-up showing at Wimbledon. Zverev stands as one of the favorites at the Shanghai Masters 1000 tournament, which gets underway on Wednesday, October 7, 2026.
Rebuilding for the Future
Reflecting on the decision to halt his year, Sinner emphasized long-term health over immediate competition. “These past few years, and particularly the end of last season in Turin, gave me so many wonderful emotions,” Sinner said in his video message. “This end of the year will be very different, but I must also think about the longevity of my career. I will do everything possible to return to 100% of my abilities.” The Italian concluded by thanking his fans and expressing hope for a swift return to competitive courts.
