Once the likes of Mike Tyson, Evander Holyfield, and Lennox Lewis could no longer sit on the throne of boxing's heavyweight division, Ukranian superstar Wladimir Klitschko owned it for a decade. He won his first belt in 1999, was named lineal champ in 2009, and held the title for six years until Tyson Fury ended his reign in 2015. Klitschko knew it was time to hang up his gloves when Anthony Joshua handed him his second straight loss three years ago today at Wembley Stadium in London in a thrilling performance from start to finish.
Joshua had won the IBF title by this point, but he was by no means a household name worldwide until he ended the career of one of the most skilled, intelligent operators in heavyweight boxing memory.
Not only did AJ beat Klitschko, but he was the aggressor for the most of the fight, showing off the athleticism and punching power that has made him one of the biggest stars in the sport.
The bout went on to be a popular pick for 2017's Fight of the Year.
Fury and Deontay Wilder might have leapfrogged Joshua in the pound-for-pound rankings after Joshua's slip-up against Andy Ruiz, but the British superstar is still capable of knocking down one of the best heavyweights ever without breaking a sweat.
