Gable Steveson Shines in Explosive DBX Debut with 15-Sec Knockout

First Round Management’s own Gable Steveson made a statement in his professional Dirty Boxing debut, securing a stunning 15-second knockout victory over Billy Swanson at The Pinnacle in Nashville.

The bout marked Steveson’s first appearance in the Dirty Boxing Championship, a fast-rising combat sport that fuses the intensity of boxing with select MMA striking techniques, including elbows and spinning backfists, while excluding grappling and kicks. The result was a showcase of Steveson’s explosive athleticism and evolving striking ability, proving that his dominance extends far beyond the wrestling mat.

Training under the guidance of Jon Jones, MMA GOAT and co-owner of Dirty Boxing Championship, Steveson entered his debut with elite mentorship and preparation. Jones, who has long admired Steveson’s Olympic wrestling pedigree, invited him to train together before his own heavyweight UFC return. Their partnership has since grown into a strategic alliance, sharpening Steveson’s all-around skill set as he builds toward a future in the UFC.

The Nashville event was also a milestone for the organization, it marked Dirty Boxing’s first event outside Miami, signaling its plans for nationwide expansion. Steveson’s performance drew major attention not only to his personal rise but also to the growing popularity of Dirty Boxing as an innovative, fast-paced combat format.

With his commanding debut and mentorship from one of the sport’s greats, Gable Steveson has firmly established himself as one of combat sports’ most promising new stars. His 15-second knockout was more than a win, it was a declaration of what’s to come.
