This fight is a rematch of their June 13 fight when after an accidental head-butt to Calderon’s head results in a cut that ended the match in a technical draw after six rounds.

The co-feature finds WBO junior lightweight champion Roman “Rocky” Martinez (22-0-1, 13 KO’s) defending his belt against Argentinean Vicente Martin Rodriguez (25-2, 13 KO’s)

  • Errol Spence v Tim Tszyu - June 2026 4/7/2026
    The clash between Spence and Tszyu had reportedly been lined up to take place in June. Tim did suffer a cut in his bout against Nurja, which could potentially delay proceedings. I am concerned that Spence has not fought for years now and having no warm up. This may show that he has not much left and cashing in. Tszyu secured a one-sided unanimous decision wi […]

  • Rene Santiago to defend his WBA and WBO junior flyweight belts in Japan 4/2/2026
    Rene’s not talked about much. Even here in Puerto Rico he’s not as well known as Xander Zayas or even Oscar Collazo. But he’s got 2 of the 4 belts in the division, and tonight he defends them against Masataka Taniguchi in Japan. Gotta hand it to him. This is his 3rd straight fight in Japan. I admire any fighter who’s willing to go halfway around the world to […]
