The American tennis player Serena Williams has pulled out of this month's French Open because she has not fully recovered from health issues.
Organisers say the former world number one hasn't fully recovered from a pulmonary embolism and a foot injury.
Serena, who has not played since last July, has dropped to 17th in the WTA rankings. She won the French Open in 2002.
Her sister Venus is a major doubt for the Roland Garros tournament having not played since January because of a hip injury.
Organisers also confirmed that former world number one Dinara Safina, who is taking an indefinite break from the sport, and Argentine Davis Nalbandian have pulled out of the tournament.
