I have already noted that Jelena Jankovic, Vera Zvonareva, Tatiana Golovin, and Dinara Safina have withdrawn from the DFS Classic. At the time I wrote the post, I did not know why Zvonareva withdrew, but it turns out that she is ill.
Thanks to On the Baseline for these other withdrawal updates:
Agnieszka Radwanska, as expected, withdrew from Birmingham because she is suffering with the same French Open-induced sore arm that has recently caused Jankovic so much trouble. (Jankovic was actually the first to report Radwanska's problem with her arm.) Chan Yung-Jan is out with a back injury, so Chuang is playing with Fujiwara. Victoria Azarenka is getting some rest and recovery.
In Barcelona, Kaia Kanepi withdrew because of a hip injury.
