Roger Federer has announced he will not play tennis again this year after undergoing further surgery on his right knee.
The 20-time grand slam champion had been recovering from surgery he underwent in February but suffered a setback in his pursuit of fitness a few weeks ago.
He says he has had to have an additional quick arthroscopic procedure on his right knee.
The 38-year-old recovered from a similar knee injury in 2016, returning to win two grand slams.
