Serena Williams’ search for a record-equalling 24th Grand Slam title will extend into another year after an Achilles tendon injury forced her to withdraw from the French Open yesterday.
The American, who turned 39 this week, had been due to play Bulgarian Tsvetana Pironkova in the second round later.
But after a warm-up, she decided the injury was too severe.
Williams, a three-time former champion at Roland Garros, said she may not play again this year.
“I warmed up and it was a very short warm-up and then I spoke with my coach and said ‘what do you think?’ she said.
“I was struggling to walk. So, that’s a tell-tale sign that I should try to recover.”
Williams had suffered the problem during her semi-final loss to Victoria Azarenka at the U.S. Open.
She had said ahead of her Roland Garros campaign that she was not at 100 percent physically but had recovered sufficiently to play.
The former world number one spoke again of the injury after her first-round win over fellow American Kristie Ahn and aggravated it while practising for her second round match.
“An Achilles injury is a real injury you don’t want to play with as it can get worse and I don’t want to get to that,” she said.
“This is not a nagging injury, it’s an acute injury. If it was my knee it would be more devastating.
“It’s just bad timing and bad luck.”
Williams said she was yet to decide whether she would play again this season, saying she needed two weeks of complete rest.
