American Andy Roddick has pulled out of the French Open because of a shoulder injury, organisers said on Thursday.
World number 11 Roddick, who has never got past the fourth round at Roland Garros, had pulled out of this week's Nice Open, saying he hurt his right shoulder at the Rome Masters.
The former world number one, who has never been at ease on clay, reached three Wimbledon finals and won the 2003 US Open.
Juan Carlos Ferrero of Spain, the 2003 Roland Garros champion, has also withdrawn from the grand slam event which starts on Sunday, organisers said without elaborating.
