Jannik Sinner has withdrawn from the US Open with a knee injury, the world No. 1 announced on Friday.

“Even though I have been working hard with my team and my medical staff, we have now had to make the difficult decision that I will not be able to compete at the US Open this year,” Sinner said in a post on X.

“We have been back on court in Monte Carlo over the last couple of days and have realised that I still need more time to recover from my right knee issue. I’m obviously very sad and disappointed, as New York has a special place in my heart. I was very much looking forward to coming back and playing in the electric atmosphere in front of the great fans there.”

The news comes a day after world No. 2 Carlos Alcaraz announced his return to the tennis court after missing the last four months with a wrist injury.

The 25-year-old Italian star has not played since Wimbledon last month, where he won his fifth career grand slam singles title.
