Former heavyweight world champion Wladimir Klitschko has retired from boxing – ruling out a rematch with Britain’s Anthony Joshua.
The Ukrainian, 41, was knocked out in the 11th round by current champion Joshua at Wembley Stadium in April.
Joshua, 27, had hoped Klitschko would sign his rematch clause for a proposed fight in Las Vegas on 11 November.
Klitschko, a two-time former champion, ends his career with a record of 64 wins and five defeats.
Klitschko, 41, ruled the heavyweight division for close to 10 years before he lost to Tyson Fury in 2015.
He returned after an 18-month lay-off to face Joshua in front of 90,000 people at the national stadium.
Klitschko was knocked down in the fifth round but rallied to drop Joshua in the seventh.
