'Rejuvenated' Serena Williams 'rearing to go' post mystery Wimbledon viral malady

World No. 1 Serena Williams prepares to return to action at the WTA's Stanford tournament, and has said that the commotion caused at Wimbledon by her viral illness had taken her by surprise.

Williams had left everyone in a shock, as the 17-time grand slam champion was disoriented, unsteady on her feet and unable to serve properly on Court No. 1 at Wimbledon. Williams' doubles match alongside her sister Venus lasted just three games, with the world number one unable to get the ball over the net when it was her turn to serve.

But now, as she prepares to return to action at the WTA's Stanford tournament, Williams said that they just said that she was really ill, and really under the weather and just wasn't doing very well, CNN reported.

Williams said that she was really scared after because she didn't realize how she felt until later and it's just like she has to keep her time, she would have the rest of her life to keep playing tennis hopefully.

The American tennis ace said that she heard a lot of the response weeks and weeks later because she didn't leave her house or her bed for a few days. But, she added that by the time that happened when she read or heard about it from other people she felt like she had already really moved on.

Williams will face the Czech Republic's Karolina Pliskova on Wednesday at the WTA's Stanford tournament.
