World No. 1 Shuts Down 2026 Campaign
World No. 1 Jannik Sinner has announced that he will not play again for the remainder of the 2026 tennis season as he seeks treatment for an ongoing right knee injury.
The 25-year-old Italian confirmed the decision on Tuesday, opting to prioritize rehabilitation over defending his title at the season-ending ATP Tour Finals in Turin, which begins on November 15.
"The last couple of years, especially the ending in Turin, have given me so many beautiful feelings and emotions, which this year is going to be way different," Sinner said in a video posted to social media. "At the moment, I also need to think about my long-term career."
Inactivity Since Wimbledon Title Defense
Sinner has not competed since July, when he defeated Alexander Zverev in four sets to capture his second consecutive men's singles title at Wimbledon. Following that victory, physical strain forced a string of withdrawals throughout the summer and autumn hard-court swings, including the U.S. Open, the Rolex Shanghai Masters, the China Open, and the Montreal Masters.
Before the knee issues sidelined him, Sinner assembled a 44-3 match record in 2026, winning six titles. His run included five consecutive ATP Masters 1000 trophies:
- BNP Paribas Open (Indian Wells)
- Miami Open
- Monte Carlo Masters
- Madrid Open
- Italian Open (Rome)
Ranking Implications and What Comes Next
Sinner’s prolonged absence until 2027 opens the door for a change at the top of the ATP rankings. With the Italian unable to defend his points from previous late-season triumphs, second-ranked Alexander Zverev remains in contention to overtake the World No. 1 spot before the year concludes.
Sinner is scheduled to focus entirely on medical recovery through the off-season, with his competitive return planned for the start of 2027.
