Serena Williams' doubles campaign at Queen's Club in jeopardy after Victoria Mboko injury‎

Serena Williams’ doubles campaign at Queen’s Club could be over after one match. Victoria Mboko, the American star's doubles partner, sustained a knee injury in her singles match against Karolina Pliskova on Wednesday. Williams and Mboko had won their opening doubles match Tuesday — in the 44-year-old Williams' return to professional tennis after nearly four years away from the sport — and are scheduled to play again Thursday.
