It is! Its an undisputed championship fight because loma won three of the belts and lopez got the other belt. Its the two best lightweights in the word fighting each other! whoever wins will be the undisputed best lightweight in the world!
Nobody talks about how Berchelt supposedly wanted the winner when Herring won his world title, but Team Berchelt doesn't want that fight. Herring been a champ for over a year, same network, same promoter. No unification tho.... did berchelt really say that? anyways that's out the window now with valdez entering the division. valdez is as close as you can get to a super fight for berchelt. much bigger than any unification fight. herring and berchelt do not have the same promoter. herring is promoted by Top rank. berchelt is promoted by a mexican company who's name I forget.
