World number three, Roger Federer, will miss his fourth French Open tennis tournament in five years after having had knee surgery in Switzerland on Wednesday. The 20-time Grand Slam champion had arthroscopic surgery on his right knee which had been bothering him for a little while.

Federer, who won his only Roland Garros title in 2009, said doctors were very confident of a full recovery. In addition to the French Open, which starts on the 24th of May, the 38-year-old will also miss the tournaments in Dubai, Indian Wells, Bogota and Miami.

Federer who reached the final of Wimbledon last year, is likely to return for grass court season in time for the third Grand Slam tournament of the year at the All England Club.
