Serena Williams withdrew from the Proximus Diamond Games in Antwerp, a Tier II tournament which starts February 11. The reason was urgent medical treatment.
Last week, Williams pulled out of the ongoing Open Gaz de France because of emergency dental surgery.
Still, the Proximus Diamond Games expects seven Top 20 players to participate, including world number one Justine Henin who will headline the tournament. Also, one wildcard is still available, and it will be given to either Nadia Petrova or Elena Dementieva.
