Roger Federer, a 20-time Grand Slam singles champion, will retire from top tennis later this month after the Laver Cup in London.
Swiss Federer, 41, has not played since Wimbledon 2021, after which he underwent a third knee surgery.
“My body’s message to me has been clear lately” said Federer.
“I’ve played more than 1,500 games in 24 years. Now I have to recognize when it’s time to end my competitive career.”
He added: “To the tennis game, I love you and will never leave you.”
Federer has struggled for the past three years with a knee problem that limits him to just three of the 11 Grand Slams held since the start of 2020.
He has not played a competitive game since losing to Hubert Hurkacz in the quarter-finals at Wimbledon last summer.
He then announced that he needed more surgeries on his knee, having had two surgeries earlier in 2020.
Only Spaniard Rafael Nadal with 22 majors and Serbian Novak Djokovic with 21 have more Grand Slam titles in the men than Federer.
Federer made his professional debut at age 16 in 1998 and won his first Grand Slam title at Wimbledon in 2003.
He concludes his career with a record eight wins in singles at the All England Club.
Federer’s last Grand Slam win came at the 2018 Australian Open, when at the age of 36 he became the second oldest man to win a major singles title in the Open era.
After first making the world rankings in 2004, he was the leading player on the ATP Tour for 310 weeks during his career – a record until he was surpassed by Djokovic in February 2021.
