Serena Williams has withdrawn from her scheduled Wimbledon doubles match with her sister Venus due to a knee injury, organizers confirmed.
The American pair, who have won the Wimbledon doubles title six times, were set to compete together on a Grand Slam court for the first time since 2022.
Williams, 44, sustained the knee injury during her singles defeat earlier in the week. She did not address the media following that match. Wimbledon officials stated she was "not able to undertake" her doubles duties.
"I'm heartbroken to have to withdraw from doubles," Williams posted on Instagram. "Coming back to compete again has been a gift, and the opportunity to play alongside Venus once more meant the world to me. I did everything I could to be ready, but unfortunately my knee just isn't ready to compete."
