A foot injury that popped up at the end of Emma Raducanu's 2025 season has lingered into 2026. The 2021 US Open champion was forced to withdraw from a highly anticipated match with Naomi Osaka at the United Cup on Sunday just hours before it was set to begin.

Team captain Tim Henman said that Raducanu's status for the rest of the event was "up in the air." After nonetheless beating Japan, Great Britain will next face Greece on Monday to decide the winner of Group E.

"We're kind of forced to put Emma on the list because if we didn't do that, then that only gives us one option," Henman said.

"The improvement that she's made has been fantastic," he added. "She's been practicing in London, really only doing static drills, to be out on the practice court and moving and playing games. She is very close."

Osaka instead faced Katie Swan, the world No. 276, in the women's singles. Osaka won, 7-6(4), 6-1, but Great Britain took the tie on the strength of wins from Billy Harris, who himself slid in for singles after Jack Draper withdrew from the event shortly after Christmas, and the mixed doubles pair of Olivia Nicholls and Neal Skupski.

Swan, 26, nearly cracked the Top 100 back in 2022, but after missing much of 2024 with injury, contemplated retiring from tennis before returning to the tour in the back half of 2025.

"I think Katie did such a good job today. You think about her journey over the last 12, 18 months, to be out there against a Grand Slam champion on a big stage like that in a huge event representing her country, I thought her performance was brilliant," Henman continued.

"Look, I'm very happy whoever plays. ... We do have options. We'll just have to wait and see."

Raducanu had previously expressed optimism for the year ahead. In Great Britain's pre-event press conference, she said she improved physically last season, which led to a resurgence back into the world's Top 30, and was hoping to keep that consistency into 2026.

"I think it's easy to think ahead about results, but the days are passing so quickly when you're focused on your own session and the things that you can control," she said. "I think I have good people around me as well now, so it makes things easier. It makes the days go by in a really fun way, enjoyable way, but at the same time putting in a lot of good work."

"I think for me it's just about stacking the good days," she added. "I've been putting in some good practices. Even if each practice isn't as perfect as you want it to be, I think just the consistency of it is the most important thing. That's what really helped me last year.

"So I just hope to carry that on and enjoy the tennis, enjoy the process of what I'm doing, which right now I am."
