Emma Raducanu is playing fellow Briton Katie Boulter in her first WTA semi-final since 2022 after opponent Fran Jones withdrew from their last-eight match in the Nottingham Open.
Jones, 23, another Briton, was scheduled to face Raducanu on Saturday in a match carried over from Friday because of rain, but was forced to pull out with a shoulder injury.
"Hopefully everyone can understand that with the big events coming up, I'm not in a position to be taking many risks," said Jones, with Wimbledon due to start on 1 July.
British number one Boulter, 27, who is the defending champion, reached the semi-finals with a two-set win over Poland's fifth seed Magdalena Frech on Friday.
