Gustavo Trujillo remained unbeaten in bare-knuckle boxing by stopping Mick Terrill at BKB 58 in Miami. Trujillo forced the referee’s intervention at 2:59 of the second round and retained the promotion’s heavyweight championship. The result moved him to 9-0 under bare-knuckle rules and gave him another finish against an opponent with genuine championship experience.
The matchup changed before fight week ended. Terrill stepped in after Mark O’Neill encountered visa problems, bringing an 11-2 bare-knuckle record and 11 knockout wins into the replacement assignment. He was not a routine late substitute: the English heavyweight had held titles in both BKB and BKFC and arrived with the size and power to punish any careless exchange.

Trujillo Extends the Fight and Still Finds the Finish
Trujillo’s first eight bare-knuckle victories had all ended in the opening round. That history created a clear question at the James L. Knight Center: what would happen if Terrill survived the initial rush? The challenger did exactly that, forcing Trujillo into a second round and making the champion show that his offense could remain organized beyond the first three minutes.
Trujillo did not abandon the pressure that built his record. He continued closing distance, placing the straighter punches and denying Terrill enough quiet time to reset his feet. The stoppage came one second before the second round ended, a timestamp that reflects sustained damage rather than a single opening exchange.
The weights underlined the physical challenge. Trujillo came in at 241 pounds, while Terrill weighed 263. Against the larger man, the champion could not afford to stand square after every attack. His ability to enter, finish combinations and remain first in the next exchange allowed him to turn activity into accumulating damage.
A Replacement Opponent Strengthens the Result
Late changes can complicate preparation for both sides. Trujillo lost the opponent around whom his camp had been built, while Terrill accepted a title fight without the same preparation window. The circumstances should be acknowledged, but they do not make the challenger unqualified. Terrill’s record and previous championships gave the fight immediate competitive credibility.
The victory also answered a modest but useful question about Trujillo’s development. He did not need to prove he could win a long championship fight, because the bout still ended early. He did prove that an opponent could take him out of the first round without making his pressure disappear. That is meaningful progress for a fighter whose dominance had previously left little second-round evidence.
Terrill’s loss does not erase the danger he brought. He survived the phase in which every previous Trujillo opponent had been stopped and made the champion work to the last second of round two. The same short notice that created his opportunity also limited the time available to build a Trujillo-specific plan.
For BKB, the result preserves a heavyweight champion with a perfect promotional record and an aggressive style. For Trujillo, the next challenge is to keep adding layers without losing the qualities that make opponents retreat. A 9-0 record invites better-prepared challengers who will study exactly how Terrill extended the fight.
- Trujillo stopped Terrill at 2:59 of round two to retain the BKB heavyweight championship.
- Terrill replaced Mark O’Neill and entered with 11 bare-knuckle knockout victories.
