Anthony Joshua undercard to feature ex-Mayweather, McGregor and Tyson fighter

Oleksandr Usyk vs Anthony Joshua II has its first undercard fight between former world champion Badou Jack and undefeated prospect Richard Rivera. Jack - who held the WBC super-middleweight strap between 2015 and 2017 - is no stranger to being a part of huge bills having featured on the undercards of Floyd Mayweather vs Conor McGregor and Mike Tyson vs Roy Jones Jr in recent years.

The Swede, now 38, is operating at cruiserweight but spent the majority of his career at super-middleweight and light-heavyweight. His opponent, Rivera is largely untested in the paid ranks and has only fought six men with winning records during his 21-fight stint.

Jack burst onto the world scene when he captured the WBC super-middleweight title from Anthony Dirrell back in 2015 at the UIC Pavilion in Chicago. He would then, retain the title against George Groves and Lucian Bute before drawing with IBF champion James DeGale in their unification bout.

Following the draw, 'The Ripper' moved up to light-heavyweight where he defeated Nathan Cleverly, picking up the WBA (regular) belt in the process. However, despite coming close, Jack never won a major world title at light-heavyweight as he drew with WBC champion Adonis Stevenson.

Back-to-back defeats to Marcus Browne and Jean Pascal slipped Jack down the pecking order prompting him to move up to 200lb after two more fights. Since making the switch to cruiserweight in 2021, Jack has gone 2-0 with two very early stoppages in the Middle East.

In both contests - which were held in Dubai - Jack stopped his opponents within two rounds. The first coming via a second-round knockout over Samuel Crossed and the last a 46-second stoppage of Hany Atiyo.
