In a video message, Sinner, 25, indicated that he and his medical team decided additional treatment was necessary. He emphasized that his priority is a complete recovery rather than returning for the concluding weeks of the season. "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.
Despite the injury, Sinner had an impressive season, securing six titles, including five ATP Masters 1000 championships, and achieving a remarkable 44-3 record prior to his injury. His standout performance came at Wimbledon, where he triumphed over Alexander Zverev to claim his fifth Grand Slam title. However, this match marked his last of the year.
Following his Wimbledon success, Sinner withdrew from both the Cincinnati tournament and the U.S. Open, and his recovery has been ongoing. Although there had been hopes for his return during the Asian swing, the need for further treatment has led him to prioritize health over competition.
Sinner's decision means he will miss the ATP Finals in Turin, where he had emerged as the champion in the previous two years, as well as other major events in the European indoor season. He expressed concern for the long-term health of his knee, stating, "At the moment, I also need to think about my long-term career. So I will do everything possible to get back 100%."
While the specifics of his knee diagnosis have not been disclosed, his management noted that he will receive treatment for inflammation. Sinner plans to take ample time to recover before commencing preparations for the 2027 season.
Sinner's absence from the tour will significantly impact the competition for the No. 1 ranking, with Zverev now poised to take the top spot. Zverev has had a defining 2026 season, winning his first Grand Slam titles at Roland Garros and the U.S. Open.
Sinner's withdrawal also curtails the evolving rivalry with Carlos Alcaraz, as injuries have limited their encounters this season. Instead of pursuing trophies, Sinner will dedicate the remainder of 2026 to ensuring his return at full strength, marking a reflective close to a season for a player known for his dominance in tennis.
