Madison Keys of the United States was forced to concede her Wimbledon third round match against Yaroslava Shvedova on Monday after failing to recover from a left thigh injury.
The 19-year-old suffered the injury in the latter stages of Saturday`s tie which was suspended due to darkness.
She was trailing 7-6 (9/7), 6-6 when play was halted having received on-court treatment for the injury.
Despite having Sunday to try and recover, Keys, who had won the Eastbourne warm-up event on the eve of Wimbledon, was unable to take her place on Court 12 for Monday`s resumption.
Shvedova, the world number 65 from Kazakhstan, goes on to face either Germany`s Sabine Lisicki, the runner-up in 2013, or Serbia`s Ana Ivanovic for a place in the quarter-finals.
Lisicki was leading their third round tie 6-4, 1-1 when their encounter was also halted late Saturday.
