American Venus Williams has pulled out of this year's Wimbledon because of a back injury, the five-times singles champion said on Tuesday.
"I will not be able to participate in Wimbledon," Williams wrote on her Facebook page.
"I am extremely disappointed as I have always loved The Championships."
Williams won her last Wimbledon title in 2008. Her sister Serena is the defending champion in this year's tournament which starts on Monday.
