Serena Williams is unlikely to play again this year after
failing to shake off a foot injury.

The American has not played since winning
Wimbledon in July after cutting her
foot in a restaurant but has trained in recent weeks with a view to
playing in the Generali Ladies Linz event in Austria this week.

But she has had to delay her comeback, revealing she has
re-strained her foot by over-training.

In a posting on her official website on Sunday, Williams said:
”I have been training for many weeks to get back to playing tennis
as quickly possible since my foot surgery in mid-July.

”Yesterday I learned that I had tried too hard, and did too
much too soon. After practising yesterday morning I felt discomfort
in my foot and tests by my doctor revealed that I had unfortunately
re-strained it, as a result of over training.

”I am likely out for the year now. I was really looking forward
to beginning my comeback in Linz, followed by the year-end
championships in Doha. I feel completely heartbroken, and
devastated, but I plan on coming back stronger and better.”

Tournament organisers confirmed Williams’ withdrawal from the
tournament in Linz yesterday.

Williams will lose her world number one spot when the latest WTA
rankings are published today, after 20-year-old Dane Caroline
Wozniacki secured top spot by reaching the quarter-finals at the
Beijing tournament.
