Serena and Venus Williams sisters to play opening doubles match at Wimbledon on Saturday‎

Serena Williams appears to have recovered enough from a knee issue in time to play doubles at Wimbledon. Serena, 44, and Venus Williams, 46, are scheduled to play their opening-round doubles match Saturday after organizers pushed it back to give Serena time to deal with a knee problem she sustained during her loss in singles. The Williams sisters' match against Camila Osorio and Solana Sierra is the only first-round doubles match yet to be played at the grass-court tournament.
