July 7 (Reuters) - Reigning ⁠women’s singles champion Victoria Mboko has ⁠withdrawn from the Canadian Open due ‌to a knee injury, the world number 10 confirmed on Tuesday.

The 19-year-old Canadian has not played ​a competitive match since slipping ⁠awkwardly while facing ⁠Karolina Pliskova at the Queen's Club Championships in ⁠June.

After ‌scans on her left knee, Mboko pulled out of her ⁠doubles quarter-final alongside 23-timesGrand Slam champion Serena ​Williams and ‌said she had injured the medial ⁠collateral ligament.

The ​injury forced Mboko to withdraw from the rest of the grass-court season, including Wimbledon.

Mboko ⁠said on Tuesday that the ​U.S. Open tune-up event in Toronto meant "everything to her".

"Not being able to play at ⁠home this summer in front of the people I love and with the support of the Toronto crowd is deeply ​disappointing as it has been ⁠something I’ve been looking so much forward ​to," she said.

The Canadian ‌Open runs from August ​2-13 in Toronto.
