Serena Williams' doubles partnership with 19-year-old Victoria Mboko at the Queen's Club Championships came to an abrupt end after Mboko suffered an injury. The Canadian teenager slipped during her singles match against Karolina Pliskova on Wednesday, forcing her retirement and subsequent withdrawal from the doubles competition.

Williams and Mboko were scheduled to face Leylah Fernandez and Laura Siegemund in the quarter-finals, but the youngster's injury meant their opponents advanced automatically via walkover. This marks another setback in Williams' return to competitive tennis following nearly four years away from the sport.

The 23-time Grand Slam champion shared an emotional Instagram post, writing that some moments mean more than trophies and expressing gratitude for the special week. She specifically wished Mboko a speedy recovery while daughter Olympia watched from the sidelines during training sessions at the west London venue.

While Williams hasn't ruled out Wimbledon, where she captured six singles and six doubles titles, the All England Club's wild card committee will deliberate next week. Officials acknowledged the excitement surrounding her comeback, particularly on grass courts, suggesting her return has generated significant buzz for the sport.
