Three Olympians have been added to a huge pay-per-view undercard.

Lawrence Okolie, Josh Kelly and Joe Cordina have, it was announced on Friday, been given the golden opportunity to box at Wembley Stadium next month.

The trio –– two of whom are yet to make their professional debuts –– will feature on a card topped by Anthony Joshua’s IBF world heavyweight title showdown against Wladimir Klitschko on April 29, exclusively live on Sky Sports Box Office, in which the pair will also vie for the vacant WBA Super and vacant IBO crowns in the sport’s premier weight class.

Okolie made a storming start to his paid campaign recently when he ousted the vastly overmatched Geoffrey Cave inside 20 seconds at the Manchester Arena on March 25.

After his statement win on the undercard of Jorge Linares’ dominant world lightweight title victory over Anthony Crolla, he was confirmed as an addition to the undercard to Ricky Burns’ WBA super-lightweight title defence against IBO and IBF world champion Julius Indongo on April 15 at the SSE Hydro Arena in Glasgow, Scotland.

And two weeks later, he is set to box on the Joshua-Klitschko bill alongside 23-year-old Kelly, of Sunderland, who campaigned at welterweight at last summer’s Rio Olympics, and Welshman Cordina.

‘Pretty Boy’ Kelly, a bronze medallist at the Baku European Games in 2015, will make his bow on the Burns-Indongo card on April 15, while Cordina turns over in Liverpool, at the ECHO Arena, on April 22, as part of the undercard to Martin Murray’s middleweight matchup against Gabriel Rosado and the vacant British super-middleweight title showdown between Rocky Fielding and John Ryder, before turning out in the capital seven days later.

Also on the Joshua-Klitschko card, the main event on which has yet to secure a US broadcaster, Scott Quigg will defend his WBA International featherweight title against Viorel Simion in what his promoter Eddie Hearn hopes will be sanctioned as a final eliminator to face the world champion which is currently Leo Santa Cruz.

Further additions to the bumper Box Office bill will be revealed in due course.

Sky Sports Box Office will show Joshua v Klitschko exclusively live on 29 April. To book go to www.skysports.com/joshua
