Ferrer through as Darcis withdraws

London - Spain's David Ferrer was on court only briefly on Thursday as Wimbledon second round opponent Steve Darcis retired injured.

Ferrer, twice a quarter-finalist at the grass-court slam, was leading 3-0 when Belgium's Darcis cried off with a back injury.

Darcis, who once beat Rafael Nadal at Wimbledon, is the eighth player to retire in the men's singles at this year's championships.

Two players - Martin Klizan and Alexandr Dolgopolov - failed to complete their matches on Centre Court against Novak Djokovic and Roger Federer respectively on Tuesday.

Unseeded Ferrer will play either Czech Tomas Berdych or American Ryan Harrison in the third round.
