Canada’s best hope of a Wimbledon women’s singles title has ended before the tournament even begins.
Mboko sustained the injury at Queen’s Club on Wednesday after an awkward fall in her singles match against Karolina Pliskova.
The 19-year-old from Burlington, Ont., got up on her own but then told a physiotherapist there was “no stability right now.”
It was Mboko’s first singles match on grass this season. The injury also forced her out of the women’s doubles draw at Queen’s Club, where she was competing alongside Serena Williams.
Mboko reached the second round in her Wimbledon debut last year. She won at least two matches in each of the first two majors this year, including a career-best fourth-round appearance at the Australian Open.
She is scheduled to defend her title at the National Bank Open presented by Rogers in Toronto in August.
