Overview
- Dirty Boxing 4 is booked for Oct. 30 at The Pinnacle in Nashville with Steveson vs. Swanson as the heavyweight main event.
- Both fighters will make their promotional debuts, and the headliner is currently the only bout announced for the card.
- DBX’s ruleset bans grappling and allows backfists, forearm, palm and elbow strikes with five-ounce MMA gloves.
- Steveson enters after a 98‑second TKO in his Sept. 12 MMA debut at LFA 217, where Jon Jones cornered him.
- Jones co-owns DBX and has publicly predicted he will coach Steveson into a future UFC championship, while Swanson brings a 4‑3 MMA mark and a recent BKFC loss.
