Johanna Konta has suffered another frustrating blow to her summer tennis season, withdrawing from the Canadian Open because of a knee injury.
The British number one was making her comeback from the effects of coronavirus in Montreal, and began her campaign with an impressive win over Elina Svitolina, coming from a set down to beat the third seed.
She was due to play Coco Gauff in the quarter-finals as she builds up to the US Open, but has pulled out due to a left knee injury.

In June, Konta admitted she may have to live with an injury to her other knee for the rest of her career, so this will be a concern for the 30-year-old, who has endured a miserable run of luck which meant she missed Wimbledon and the Tokyo 2020 Olympics.
In a tweet, the WTA Tour said: "Johanna Konta has withdrawn from Montreal due to a left knee injury. Coco Gauff advances to the quarter-finals via walkover, will face either (Petra) Kvitova or (Camila) Giorgi."
Konta was unable to compete at Wimbledon after a member of her team tested positive for Covid-19, and she then picked it up herself in the lead-up to the Games in Japan.
Montreal was her first event since winning the grass court Nottingham Open three months ago.
