World number one Jannik Sinner has been ruled out for the remainder of the 2026 season after a right‑knee injury. The injury will prevent him from playing again this year, ending his campaign prematurely, as the ongoing problem forces him to miss the remaining ATP events, including the year‑ending championships.
Sinner’s withdrawal could open the door for Germany’s Alexander Zverev to finish the year atop the ATP rankings, potentially reshaping the top spot for 2026 as the German contender gains momentum in the closing tournaments this season.
