Devin Haney vs. Jo Jo Diaz: The Big Fight Preview - Everything you need to know

Devin Haney vs. Joseph Diaz Matchroom Boxing

The lightweight division holds its breath as there is another title on the line, just a week after Teofimo Lopez lost his WBC franchise, WBA, IBF and WBO titles to Australian mandatory challenger George Kambosos Jr.

There appears to be no rematch on the cards between the pair as Lopez looks for a move up to 140lbs in his next fight.

That leaves a potential undisputed clash on the cards between the winner of Saturday's fight in Las Vegas between Devin Haney and his own mandatory challenger, Joseph 'Jo Jo' Diaz Jr.

The winner will doubtless be tempted to set up a 2022 clash to finally settle the question of the real WBC champion, and also to chase glory at 135lbs.

As well as the main event, there are some notable fighters on the undercard, such as Croatian heavyweight Filip Hrgovic and undisputed women's welterweight champion Jessica McCaskill, who will defend her four world titles against Victoria Bustos. 

Here are all the details for Haney vs Diaz.
