“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,” Jannik Sinner said in a video message on Instagram. The world number one won’t compete again this year. His focus now is recovery, while the sport’s top ranking remains open to challenge.
A ranking without its number one
A knee injury has kept Sinner out of action since Wimbledon in July. He hasn’t played since beating Alexander Zverev in the All England Club final on July 12. Now, the top-ranked player is stepping away from the competition that determines who holds that spot.
The absence reaches across the tennis calendar. Sinner missed the North American hardcourt swing, the US Open and tournaments in Asia. He’ll also miss the European indoor hardcourt swing and the season-ending ATP Finals in Turin, where he won the title in the last two years.
The rankings keep moving, even when their leading player can’t compete. German world number two Zverev could finish the year at the top. He has cut the gap to Sinner after winning the French Open and US Open titles. Sinner’s withdrawal doesn’t settle the final ranking, but it gives Zverev a chance to overtake him.
Recovery on the player’s terms
Sinner said he needs to think beyond the current season. “I also need to think about my long-term career so I will do everything possible to get back 100 per cent,” he said. Recovery comes before a return to the tour, while he’s still not ready.
His team said he’ll undergo treatment for inflammation in his knee. “The decision has been made to have the treatment now to give Jannik the necessary time to recover before beginning preparations for 2027,” the team said. Sinner and his team have laid out a plan: treatment now, preparation for a later return, and no attempt to force a comeback into the remaining tournaments.
There’s no broader policy fight in the account of Sinner’s withdrawal, and no grassroots campaign or mutual-aid response is reported. The player made the decision with his doctors, while the team explained the treatment plan. The competitive system keeps counting. Tournaments continue, titles are contested, and the ranking can change in his absence.
For now, the consequences are clear. Sinner’s season is over, the ATP Finals in Turin will go ahead without the player who won the title in the last two years, and Zverev has a chance to finish the year at number one. The world number one has chosen time to recover. The rankings won’t wait for anyone.
