Five-time Wimbledon champion Venus Williams has pulled out of this month's tournament because of an ongoing lower back injury.
Williams suffered her earliest French Open exit in 12 years when she crashed to a first-round defeat to Poland's Urszula Radwanska at Roland Garros last month.
The 33-year-old - who has won seven Grand Slam titles in all - also pulled out of the doubles there with her sister Serena because of her back problem.
Venus Williams is currently ranked 34 in the world.
Wimbledon starts next week.
