Cape Town - Swiss tennis ace Roger Federer has pulled out of the Rotterdam and Dubai ATP tournaments after undergoing knee surgery.
Federer announced on Wednesday that he injured his knee a day after losing to Novak Djokovic in the Australian Open semi-finals last week.
The 17-time Grand Slam champion is currently ranked third on the official ATP rankings.
Federer, 34, posted the following message on his official Facebook page on Wednesday:
"I want to inform you that yesterday I underwent arthroscopic surgery on my knee. I injured my knee the day after the semi-finals in Australia. After getting tests done when I returned home, it was determined that I had torn my meniscus. I apologise to my friends in Rotterdam and Dubai, as I was very much looking forward to playing those events. While this is an unfortunate setback, I am encouraged and grateful that my doctor said the procedure was a success. I am looking forward to attacking the rehabilitation process this afternoon with my team and working hard to get back out on tour as soon as possible. Thanks for all your incredible support. I will check in with all of you soon."
