Overview
- The BKB 58 card, set for Saturday, August 29, 2026 at Miami’s James L. Knight Center, was reshuffled after Mark O’Neil withdrew because of visa problems.
- Yuriorkis Gamboa’s bare‑knuckle debut was promoted to the main event when he was paired with Yesner Talavera in the Trigon ring.
- Gustavo Trujillo, who is 8-0 in BKB with eight first‑round KOs and 12-0 as a pro boxer, will no longer defend his heavyweight title and now faces Jarome Hatch in a non‑title co‑main fight.
- The card still includes three championship bouts and other high‑profile appearances, including Aspen Ladd’s BKB debut against Bianca Daimoni.
- Broadcasters for the event include TikTok, Swerve TV, Adrenaline Plus, Vice TV and Telemundo Deportes Ahora, and the late lineup change highlights logistical risks for international matchups that could affect future bookings and the promotion’s growth plans.
