Serena and Venus Williams are the latest high-profile stars to withdraw from the 2021 Western & Southern Open, joining Roger Federer and Novak Djokovic.
Serena, a two-time Western & Southern Open champion, withdrew because of her leg injury; however, officials did not provide a reason for why Venus would not be competing.
“Unfortunately, I will not be playing in the Western & Southern Open next week as I am still in recovery from my leg injury at Wimbledon,” Serena said in a W&S Open press release. “I will miss all of my fans in Cincinnati whom I look forward to seeing every summer.
