San Francisco Frontiers - Krejcikova suffers injury scare ahead of Wimbledon defence

Krejcikova was due to face France's Varvara Gracheva in the quarter-finals at Devonshire Park, but announced her withdrawal just hours before the match.

The world number 17 suffered the problem on Wednesday during her second-round victory over Britain's Jodie Burrage.

The injury worsened overnight and, with her Wimbledon first-round tie scheduled for Tuesday, the 29-year-old opted not to risk aggravating it.

Krejcikova is awaiting the outcome of a scan before deciding if she will be fit to chase a second successive title at the All England Club.

"I'm very sorry to have to withdraw from my quarter-final today in Eastbourne as I'm having some soreness in my right thigh," Krejcikova said.

"Overnight it just didn't get any better, it actually got worse. I think it's better with Wimbledon in the next couple of days just to rest it and to see what's going on and to resolve that."

Krejcikova has endured a difficult time since defeating Italy's Jasmine Paolini in the women's singles final at Wimbledon last year.

She lost in the second round of the recent French Open and also missed January's Australian Open with a back injury, which kept her sidelined until May.

Krejcikova made a poor start to the grass-court season with a shock loss against Slovakia's Rebecca Sramkova in the first round at Queen's Club earlier this month.

The two-time Grand Slam champion had to save two match points before beating Britain's Harriet Dart in the Eastbourne first round.

The second seed saved three more match points against Burrage.
