Serbian second seed Jelena Jankovic reached the Wimbledon last 16 on Saturday but admitted she's facing a fitness battle to make her fourth round clash after picking up a knee injury.
Jankovic came from behind to beat Danish 30th seed Caroline Wozniacki 2-6, 6-4, 6-2 to make the second week for the third successive year. However, she slipped badly on the Centre Court surface in the first set, jarring her left knee.
The 23-year-old had to have the knee bandaged at the changeover before going onto secure a two-hour victory over Wozniacki, the 2006 junior champion. "I slipped and my leg went straight. I started to feel pain. It was a struggle so I needed treatment," said Jankovic.
The injury scare was the latest Grand Slam setback for Jankovic who needed regular treatment on her shoulder during her run to the semifinals at the French Open.
Watched by a royal box packed with a host of sporting stars such as Indian cricketer Sachin Tendulkar and English football legends Bobby Charlton and Geoff Hurst, Jankovic was under the cosh in the first set. The Serbian world number two slipped to a 4-2 deficit as her game fell to pieces. Wozniacki, the daughter of a professional footballer, then held her nerve in the eighth game where she wasted five set points before securing the opener on her sixth when Jankvovic hit long.
