The Williams sisters reunion will have to wait.

Serena and Venus Williams withdrew from Wimbledon doubles competition Saturday due a knee injury Serena sustained during her singles match Tuesday against Maya Joint.

Williams posted a video of her walking gingerly and photos of several syringes of fluid removed from her knee on Instagram on Saturday morning

“Coming back to compete again has been a gift, and the opportunity to play alongside [Venus] once more meant the world to me,” she wrote. “I did everything I could to be ready, but unfortunately my knee just isn’t ready to compete.”

On Tuesday, Serena fell in three sets to Joint, 20, in the first round of the women’s singles competition, though Serena received mass support from the crowd at Centre Court.
