Wladimir Klitschko announces retirement from boxing
REUTERS - Former heavyweight world champion Wladimir Klitschko announced his retirement from boxing on Thursday, ruling out a rematch with Briton Anthony Joshua.
The 41-year-old Ukrainian was knocked out by Joshua in the 11th round at Wembley Stadium in April.
Klitschko announced his retirement on his website (www.klitschko.com), and posted a video on his offical Twitter account after his website's server broke down.
