Johns Scores Comeback TKO After Short-Notice Swap at UFC Vegas 120
A UFC physician’s decision to pull Jessie Rosas led to a 145-pound short-notice bout that gave Gianni Vazquez a two-day call-up and ended in his first knockout.
Overview
- Miles Johns recovered from an early knockdown and stopped Gianni Vazquez by TKO at 3:09 of Round 1 on Saturday, Aug. 8, 2026.
- Jessie Rosas was not cleared to fight because of a forehead wound, which prompted the UFC to book Vazquez on roughly two days’ notice and move the bout up to 145 pounds.
- The victory snapped Johns’s reported three-fight skid and returned him to the win column, although outlets differ on the exact date of his prior win.
- Vazquez absorbed the first knockout loss of his pro career after accepting the emergency call-up following a recent release and a regional victory.
- The late change highlights how UFC medical clearances and flexible matchmaking preserve live cards by shifting weight classes and using short-notice regional signees, a practice that raises preparation and safety risks for fighters.
