Williams cut her right foot on broken glass at a restaurant shortly after winning her fourth Wimbledon title.

The 13-time Grand Slam champion said Saturday that she would miss events in Istanbul, Cincinnati, and Montreal prior to the US Open, the last Grand Slam of the year which starts on August 30 in New York.

“Hey guys I'm doing better,” Williams tweeted Monday. “Thanks for all the love.”

But WTA tour spokesman Andrew Walker said on Monday that Williams is questionable for the final Grand Slam of the year.

Williams' World Team Tennis team, the Washington Kastles, said she needed stitches on the bottom of her foot.

On Sunday night she tweeted that she was anxious to get back to work.

“Can't wait to get out of bed & back on the courts & do what I do best!” she wrote.

Williams fell in the semi-finals of last year's US Open to eventual champion Kim Clijsters in a match marred by the American's abusive tirade toward a line judge.

Williams was fined a record 175,000 dollars with the amount to be reduced to 82,500 dollars if she remains on good behavior for two seasons. - AFP
