ROGER FEDERER has had knee surgery and expects to miss tournaments in Rotterdam and Dubai this month.

    “Roger Federer underwent successful arthroscopic knee surgery today in Switzerland to repair a torn meniscus,” a statement on his official website said Wednesday.

    It is a rare injury setback for the 34-year-old Federer, who has had relatively minor back problems in 2008 and 2013.

    The statement did not specify which knee is injured, though it said it happened last Friday, one day after his Australian Open semifinal loss against Novak Djokovic.

    “My doctors have (assured) me that the surgery was a success and with proper rehabilitation, I will be able to return to the Tour soon,” Federer said.

    His next scheduled tournament is a Masters 1000 event at Indian Wells, California, starting March 7.

    “I apologize to my friends in Rotterdam and Dubai, as I was very much looking forward to playing those events,” Federer said.
