World number one Jannik Sinner will miss the rest of the 2026 season while he receives treatment for a knee injury, ending his competition year after absences that began following Wimbledon in July. He’ll miss the European indoor hardcourt swing and the ATP Finals in Turin, giving Alexander Zverev a chance to finish the year atop the rankings.
The Treatment Decision
Sinner announced his decision in a video message on Instagram. “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,” he said. “I also need to think about my long-term career, so I’ll do everything possible to get back 100 per cent.”
His team said the treatment would address inflammation in his knee. In a statement, it said: “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 cited recovery and preparation for next season as reasons for choosing treatment now.
Sinner hasn’t played since July 12, when he beat Alexander Zverev in the All England Club final. The injury has kept him out of action since Wimbledon. The report gives no treatment-cost, earnings or sponsorship figures, and doesn’t identify any labor organization or government role in the decision.
A Season of Withdrawals
The 25-year-old missed the North American hardcourt swing, the US Open and tournaments in Asia. His latest decision adds the European indoor hardcourt swing and the season-ending ATP Finals in Turin to the events he won’t play in 2026.
Sinner won the ATP Finals title in each of the last two years. He’ll miss the Turin tournament, where he was the defending champion. The report doesn’t say how his absences affected tournament revenues, other players’ earnings or commercial agreements.
His announcement ties the decision to medical treatment and the length of his career. Sinner said he would do everything possible to return “100 per cent,” while his team said treatment would give him time to recover before preparations for 2027 begin. Neither statement gave a date for his return to competition.
Rankings and the Tournament Field
German world number two Zverev has cut the gap to Sinner after winning the French Open and US Open titles. Sinner’s absence could give Zverev the opportunity to finish the year at the top of the world rankings. The article identifies that possible change but gives no points gap or explanation of how the final standings will be determined.
The report focuses on Sinner’s injury, treatment, missed tournaments and ranking implications. It contains no account of player organizing, workplace disputes, policy proposals or state action. The confirmed change is to Sinner’s schedule: he won’t compete again in 2026, and his team says he’ll recover before preparing for 2027.
