The US Open field lost another legend.
Venus Williams withdrew from next week's US Open with a leg injury hours after younger sister Serena Williams pulled out as she continues recovery from a hamstring injury. Venus' exit means for the first time since 2003 neither Williams sister will be in the US Open field.
More: Serena Out of US Open
Sofia Kenin, the 2020 Australian Open champion, and former Wimbledon finalist Milos Raonic have also pulled out.
The 41-year-old Venus was set to make her record-extending 23rd US Open appearance. Instead, she joins sister Serena and fellow former US Open champions Roger Federer, Rafael Nadal, Stan Wawrinka and reigning champion Dominic Thiem in withdrawing.
"It's super, super, super disappointing," Venus Williams said in a video which she posted on social media. "I'm having some issues with my leg all this summer, and just couldn't work through it.
"I tried my best here in Chicago, but I just was unable to figure out the equation. And there's been so many times where I've been able to figure it out, even not in the best of my health, but this time, I just couldn't make any miracles work."
Venus, who reached the US Open final in her 1997 Flushing Meadows debut, said she'll be a fan watching the season's final major unfold on television.
"In all seriousness, I am really disappointed," Venus said. "It's a tough time right now, but like all tough times, they don't last forever. "Regardless, I'm wishing all players the best of luck this year.
"Be well, don't get hurt like I did. Stay safe, and everybody enjoy the US Open, I know I'll be watching from home."
