Roger Federer is unranked for the first time in 25 years on Monday after missing out on the last 12 months due to injury.
Federer had appeared in the singles rankings every week since he made his debut at age 16 in September 1997, tied for 803rd, and was ranked No 1 for 310 weeks.
The Swiss, who turns 41 in August, has not played since Wimbledon 2021 as he underwent a third knee surgery shortly after his loss in the quarterfinals.
Federer was 97th before play began at the All England Club but now has zero points because the rankings are based on a player’s results over the previous 52 weeks.
The 20-time major champion is expected to make a comeback at the Basel Open in September.
Wimbledon champion Novak Djokovic also dropped down to No 7 in the rankings.
Though he defended his title at SW19, Djokovic could not regain his World No 1 spot as ATP and WTA had stripped Wimbledon of ranking points.
The governing men’s and women’s tennis bodies had taken the decision in the wake of the All England Club banning players form Russia and Belarus over the war in Ukraine.
Australia’s Nick Kyrgios, who finished runners-up at Wimbledon, went from No.40 to No.45 despite reaching the first Grand Slam final of his career.
Russia’s Daniil Medvedev retained his top spot in men’s rankings.
