Tennis great Roger Federer is no longer ranked by the ATP Tour after his remaining ranking points expired, meaning he has dropped out of the top 100 for the first time this century.

The 40-year-old has not played since undergoing knee surgery after a straight-sets defeat to Hubert Hurkacz in the quarter-finals at Wimbledon in 2021, having also missed much of the 2020 season with a similar injury.

But Federer, a 20-time grand slam champion, has repeatedly ruled out retiring and recently said he intends to make an ATP Tour comeback in 2023.

His remaining ranking points have now expired, meaning he has not only dropped out of the top 100 for the first time in almost 23 years, but he is no longer ranked at all by the ATP.

According to Opta, the last time the Swiss superstar was not ranked among the 100 best players in the world was October 4, 1999, a remarkable 8,316 days ago.

Daniil Medvedev remains as world number one, while Wimbledon champion Novak Djokovic slipped to seventh in the rankings despite his win over Nick Kyrgios at SW19 on Sunday, as ranking points were stripped in this year's tournament.
