Serena needs foot surgery, will miss 3 events

New York :

Serena Williams needs surgery on her right foot after cutting it on a broken glass at a restaurant.

The top-ranked women's player was injured last week and will miss three tournaments leading to the US Open, the WTA Tour said on Saturday.

Williams has withdrawn from tournaments in Istanbul, Cincinnati and Montreal. The tour website offered no details about what happened at the restaurant.

"I'm so upset I won't be able to play in the upcoming events because of this foot surgery," Williams said on the website. "Thank you for all of your support. I can't wait to get back on the courts."

A message left with her agent was not immediately returned.

On July 8, days after winning her fourth Wimbledon crown and 13th major title, Williams played with an injured foot against Kim Clijsters in an exhibition in Brussels before a world record tennis crowd. On July  10, she attended the wedding of NBA star Carmelo Anthony in New York. In a photo, it appeared she had two bandages on the top of her right foot.

The Rogers Cup in Montreal begins on Aug 16, and the U S Open starts on Aug 30.

After winning the Australian Open at the end of January, Williams was sidelined through April because of an injured left knee. She lost in the French Open quarterfinals in June before capturing Wimbledon.
