Serena Williams has withdrawn from the French Open ahead of her second-round match against Tsvetana Pironkova due to an Achilles injury.
The 23-time Grand Slam champion was scheduled to meet Pironkova on Court Philippe-Chatrier on Wednesday morning but pulled out ahead of the contest.
Williams went into the tournament managing an Achilles problem that she sustained at the US Open and was not been able to recover sufficiently after her 7-6 (7-2) 6-0 first-round victory over Kristie Ahn.
