Five-times champion Venus Williams withdrew from The Championships 2013 on Tuesday, posting on her Facebook page that an ongoing injury was setting her out of competition until next month.
"Unfortunately, I will not be able to participate in Wimbledon this year," wrote the American, who celebrated her 33rd birthday on Monday. "I am extremely disappointed as I have always loved The Championships, but I need to take time to let my back heal."
Williams won at the All England Club in 2000, 2001, 2005, 2007 and 2008. Last year, she lost in the first round for the first time since she made her debut at Wimbledon in 1997. The world No.34 was due to make her 17th straight appearance at the tournament.
"I look forward to returning to the courts as soon as possible," Venus continued. "Many thanks to my fans for the love and support and I will be seeing you very soon back on the courts."
