World number one Jannik Sinner has pulled out of the upcoming US Open with a knee injury.
The 25-year-old Italian has not played competitively since winning the Wimbledon title in July.
"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.
"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."
