Serena Williams has her sights set on defending her Wimbledon title as she recovers from emergency surgery to remove a blood clot in her lung.

18289 - Serena targets Wimbledon return

The 13-time grand slam champion suffered a health scare when she had a pulmonary haematoma removed on Monday and revealed the ordeal had been "extremely hard, scary and disappointing".

Williams has not played since winning Wimbledon in July last year after cutting her foot on some glass, and after her latest setback her priority is now a return to fitness.

"Thank you everyone for all of your prayers, concerns, and support," Williams said in a statement. "This has been extremely hard, scary, and disappointing. I am doing better, I'm at home now and working with my doctors to keep everything under control.

"I know I will be okay but am praying and hoping this will all be behind me soon. While I can't make any promises now on my return, I hope to be back by early summer. That said, my main goal is to make sure I get there safely."
