The promotion’s inaugural event featured familiar names like former PFL prospect Solomon Renfro and former UFC light heavyweight Fabio Cherant. In an unprecedented move, Perry and Dirty Boxing won’t stream the fights live, and will instead opt to release the fights the day after on its platforms.

Yoel Romero is fighting this weekend. Yes, you read right. The former multiple-time UFC title challenger returns to action this Saturday in Miami, Fla., at Dirty Boxing Championship – a striking promotion owned by Mike Perry.

Like much of Dirty Boxing's debut show, which was held as a private event at an undisclosed location in Miami, Romero’s involvement was kept under wraps until he unexpectedly showed up to Friday's weigh-in for a heavyweight showdown against Power Slap veteran Duane Crespo.

Yoel Romero still has it at 47 years of age. The former UFC title challenger helped ring in the debut event for Dirty Boxing Championship (DBC), which is a promotion created by bareknuckle brawler and former UFC fighter Mike Perry.
