"JoJo" Diaz was set to defend his WBC interim lightweight belt against Ryan Garcia, but the 29-year-old slugger now has a shot at the real thing, and he doesn't need to delve into the Rocky archives for underdog inspiration.
George Kambosos' beating of unified lightweight champ Teofimo Lopez last weekend sent shockwaves through boxing circles, and should give Diaz all the belief he needs.
"The Dream", six years his opponent's junior, was jeered by large sections of the crowd after beating former three-weight champ Jorge Linares. Haney dominated the fight but was hurt late on and just about held on for victory.
He's got plenty to prove, and here's how to watch Devin Haney vs Joseph Diaz Jr online and get a live stream, no matter where you are in the world.
