TOKYO (Reuters) -- World No. 2 Serena Williams has pulled out of next week's Pan Pacific Open with knee and toe injuries, organizers said on Thursday.

The Australian Open and Wimbledon champion has not played a singles match since her rant at a lineswoman in her semifinal loss to Belgian Kim Clijsters at the U.S. Open earlier this month.

The rest of the women's world top 10, including Serena's older sister Venus, is among the field at the $2 million event.

World No. 1 Dinara Safina, who was not on the initial entry list, has opted to compete in Tokyo in a bid to retain the Pan Pacific crown she won last year.
