Serena Williams withdraws from exhibition after foot surgery Serena Williams, shown during the 2012 Olympics, has had sugery on both of her big toes and will miss an exhibition match next week. She is expected, however, to be ready for the 2013 Australian Open next week. BANGKOK, Dec. 19 (UPI) -- Serena Williams has had surgery on her toes, leading to her withdrawal from next week's exhibition in Thailand, officials said. Williams, 31, was treated for a "chronic foot disorder," Dr. Jeffrey Rockefeller, a podiatrist, said. The procedure was performed on both of Williams' big toes. Rockefeller said the operations were "minor" but Williams "needs to minimize activity to fully recover." Williams, however, is expected to play in next month's Australian Open. Williams was selected the WTA Player of the Year for 2012 after winning Wimbledon, the Olympics, the U.S. Open and the WTA Championships in the second half of the year. Exhibition organizers said Li Na would replace Williams for the Dec. 29 exhibition match against No. 1-ranked Victoria Azarenka in Hua Hin, Thailand. The Australian Open is scheduled to begin Jan. 14.
