World number one Jannik Sinner withdraws from the 2026 US Open because he is unable to recover in time from a persistent right knee injury. Multiple outlets report that he makes the decision after medical and training efforts, and that he announces he will not be ready for the start of the main draw on August 30.
Reports describe the injury as lingering and present during Sinner’s lead-up to New York. Some outlets add that he pulls out of hard-court warmups in Montreal and Cincinnati, where he previously planned to compete. Several accounts note his first missed Grand Slam since 2019. The timing of the withdrawal also affects the men’s draw: Rappler and others say Carlos Alcaraz is positioned as a leading contender, especially since Alcaraz has been returning from a separate right wrist injury and is reported fit to play.
Across coverage, the emphasis is on Sinner’s withdrawal and the knee’s impact, with contextual differences around his prior results and injury history. Some outlets also mention his past Grand Slam record, including his status as Wimbledon champion and his recent US Open performance.
