Wimbledon withdrawal for Keys

American teenager Madison Keys 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.

A despondent Keys took to Twitter to apologise for not being able to continue, saying: \"So sorry I couldn't go out and finish the match tomorrow. Big good luck to @SlavaSays in the next round!\"

Shvedova, the world No 65 from Kazakhstan, progresses to the round of 16, where she will 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; the pair will resume on Monday afternoon.
