Serena Williams has officially withdrawn from the US Open. The world no.1 says from a statement she still needs time to recover from foot surgery.
Williams last played at the exhibition match against Kim Clijsters in Belgium. She replaced the injured Justine Henin, who has ended her season due to her elbow injured from Wimbledon.
Ironically, Clijsters also injured her thigh earlier today in her loss to Vera Zvonareva in Montreal. The Belgian lost in three sets.
