TOKYO: World number one Serena Williams has withdrawn from next week`s Pan Pacific Open in Japan because of injury, organisers said on Thursday.

Williams cut her foot on broken glass at a restaurant shortly after winning her fourth Wimbledon crown in July. Tournament organisers said the 13-time Grand Slam winner had not fully recovered after an operation on the injury, which also forced her out of the US Open.

Most of world`s top 30 players will take part in the two million dollar hard court tournament in Tokyo from September 26 to October 2.
