JoJo Diaz lost his IBF super featherweight title after he missed the 130 pound limit by 3.5 pounds in his last fight. It's very rare to see a professional boxer, let alone a world title holder, miss weight by so much. Many experts say he didn't look very good in that fight (vs. Shavkatdzhon Rakhimov) either, but it has to be taken into account that he fought a young, undefeated guy who also is a big puncher (15-0, 12 KO's). For this fight, 28-year-old JoJo Diaz (31W-1L-1D) goes up into the 135 pound division to battle against 31-year-old Javier Fortuna (36W-2L-1D) for the vacant WBC interim lightweight title. Javier hasn't been defeated since 2018 and comes as the naturally-bigger man, but he is slightly older than JoJo. The winner of the Diaz vs. Fortuna fight will be mandatory for the current WBC champion, Devin Haney.
