LONDON (AP) — Serena Williams’ doubles campaign at Queen’s Club could be over after one match.
Victoria Mboko, the American star’s doubles partner, retired from her singles match against Karolina Pliskova on Wednesday after sustaining a knee injury in the second set.
Williams and Mboko had 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.
The 19-year-old Canadian slipped behind the baseline and immediately grabbed her left knee while facing Pliskova. Mboko lost the first set 6-2 and was up 4-3 in the second and trying to break with Pliskova serving at deuce.
Mboko got up on her own but then told a physiotherapist there was “no stability right now.”
She walked gingerly to her bench and put a towel to her face as she sat down. Minutes later, she retired from the match.
Williams had previously announced that she will also play next week.
On Tuesday, Williams and Mboko beat third-seeded duo Nicole Melichar-Martinez and Erin Routliffe 7-6 (2), 6-2 in Williams’ first professional match . They’re scheduled to face Leylah Fernandez and Laura Siegemund in the quarterfinals.
Mboko is ranked No. 9 in singles.
