Six-time champion Serena Williams has been forced to pull out of the upcoming US Open.
The 39-year-old withdrew from her first-round match at Wimbledon in June after she slipped on the grass-court surface and has not recovered in time to take part at Flushing Meadows over the next two weeks.
"Serena Williams will miss the 2021 US Open due to injury," a statement on the tournament's Twitter page read.
Williams revealed in a post on Instagram she had decided to allow her torn hamstring to recover fully.
She said: "After careful consideration and following the advice of my doctors and medical team, I have decided to withdraw from the US Open to allow my body to heal completely from a torn hamstring.
"New York is one of the most exciting cities in the world and one of my favourite players to play - I'll miss seeing the fans but will be cheering everyone on from afar. Thank you for your continued support and love."
