Serena Williams will not compete with Venus Williams in the doubles after she was forced to withdraw from their first-round match due to the knee injury sustained in her singles return at Wimbledon.
Williams had been in a race to be fit to face Camila Osorio and Solana Sierra on Saturday afternoon. But she has not recovered from twisting her knee in the first set of her opening-round singles match against Maya Joint, which she lost 6-3, 6-7 (6), 6-3.
