World No. 1 Jannik Sinner Ends 2026 Season Due to Knee Injury
World No. 1 Jannik Sinner announces the end of his 2026 tennis season to undergo treatment for a persistent knee injury.

Tennis superstar and world number one Jannik Sinner has officially brought his 2026 campaign to an abrupt halt. The Italian sensation announced on Tuesday that he will undergo medical treatment for a persistent knee injury, effectively ending his season ahead of schedule.
In a personal video shared via Instagram, the 25-year-old athlete explained that the decision was made in consultation with his medical team. Sinner emphasized that while the timing is difficult, the priority must be his long-term career and ensuring he returns to the court at full fitness.
Prioritizing Long-Term Health
The decision comes after a period of inactivity for the Italian star. Sinner has not stepped onto a competitive court since his historic victory at Wimbledon in July, where he secured his fifth Grand Slam title. His absence was marked by withdrawals from major tournaments during both the North American hard-court swing and the Asian swing.
"Me together with the doctors have decided that I need a course of treatment for my knee, which means that the 2026 season is officially over,"Sinner stated in his announcement. He expressed gratitude to his supporters and voiced his determination to return to 100% health. "I will thank you already in advance for your support, and hope to see you very, very soon on court again. Ciao, ciao."
A Season of Unprecedented Dominance
The premature end to his season is a significant blow to the tennis world, considering the extraordinary heights Sinner reached earlier this year. Before the injury forced him sidelined, the Italian achieved the rare "Career Golden Masters" feat. This prestigious milestone was completed after he secured five consecutive ATP Masters 1000 titles in Indian Wells, Miami, Monte-Carlo, Madrid, and Rome.
Sinner’s 2026 season was defined by a historic 30-match winning streak, a run that was only halted during the second round of Roland Garros. His dominance has also been cemented at the ATP Finals in Turin, where he has become a two-time defending champion, winning the titles in 2024 and 2025 without dropping a single set.
Sinner's Statistical Legacy
As the world number one prepares for rehabilitation, his record at the season-ending tournament remains formidable. Key highlights of his career include:
- ATP Finals Record: 15-2 win-loss record.
- Grand Slam Success: Five Grand Slam titles, including Wimbledon 2026.
- Career Milestone: Completed the Career Golden Masters.
- Winning Streak: Achieved a career-best 30-match winning streak earlier this year.
