Emma Raducanu faces a race to be available to participate for Britain in next month’s Billie Jean King Cup finals after another tournament withdrawal. The 21-year-old posted on X that she was pulling out of next week’s Hong Kong Open because of a shortage of match fitness.

Raducanu has not played since retiring midway through her quarter-final against Daria Kasatkina in the Korea Open last month and revealed she had sprained ligaments in her foot. “I’m sorry to say that I will not be able to play in Hong Kong next week. Whilst my foot is making good progress, I need a little more time before I am match fit,” she said.

The world No 55 said she was “doing what I can” to be ready for the Billie Jean King Cup finalsBritain take on Germany on 15 November and the winner will face the defending champions, Canada, in the quarter-finals, who received a bye.

Hong Kong is the fifth tournament the British No 2 has withdrawn from after her latest setback. Since her US Open victory in 2021 she has been struggling with a number of fitness problems, most notably ankle and wrist injuries that required surgery.
