Serena Williams withdraws from Dubai

It is no surprise that Serena Williams has withdrawn from the Barclays Dubai Tennis Championships; she has been having difficulty with her leg.

Dinara Safina, struggling with a back injury, has also withdrawn, and it appears that Ana Ivanovic, who complained of shoulder pain during Fed Cup play, has withdrawn, too.

Caroline Wozniacki will be the number 1 seed in Dubai.
