Serena Williams Won't Play Doubles at Wimbledon Due to Knee Injury

Tennis legend Serena Williams had to skip her doubles match with sister Venus at Wimbledon on July 4, after injuring her right knee during her singles match against 20-year-old Maya Jolt. It was supposed to be their first Grand Slam doubles tournament together in four years. Williams, 44, suggested on Instagram that more might be coming: "stay tuned to a city near you."
