Foot injury sidelines Serena

World number one Serena Williams will miss three tournaments ahead of the US Open after cutting her foot on broken glass in a restaurant last week.

The 28-year-old underwent an operation after suffering the injury and has been ruled out of the hardcourt events in Istanbul, Cincinnati and Montreal.

The last of those events, the Rogers Cup in Montreal, begins on August 16 with the US Open commencing at Flushing Meadows a fortnight later.

“I’m so upset I won’t be able to play in the upcoming events because of this foot surgery,” Williams told the WTA Tour website, www.wtatour.com.

“Thank you for all of your support. I can’t wait to get back on the courts.”

Williams has not played on the WTA Tour since winning her 13th grand slam title at Wimbledon, when she beat Vera Zvonareva in straight sets earlier this month.
