Top-ranked tennis player Jannik Sinner has withdrawn from the U.S. Open due to a right knee injury. The withdrawal comes just days after he was expected to compete in the tournament. Sinner, who won the 2024 U.S. Open, had previously lost to Carlos Alcaraz in the final last year. His absence means the highly anticipated rivalry between the two players will not be renewed at Flushing Meadows. Alcaraz, who has been sidelined for over four months with a wrist injury, recently announced he was fit to compete. Sinner’s injury was confirmed by his team, but no further details were provided. The U.S. Open is set to take place in New York, and fans will be watching for updates on both players’ statuses in the coming weeks.
