Why this main event hits different
Oliveira returns home looking to reset after a June setback to former featherweight king Ilia Topuria. “Do Bronx” still owns the UFC records for most finishes and submissions, and his front-foot offense remains lethal. Across from him is Gamrot, an elite chain-wrestler with relentless scrambles and top control. It’s BJJ traps versus pace wrestling, and the small edges—wrist control, cage turns, back-takes—could decide the night.
Form guide and recent tape
Gamrot’s last outing was a measured decision over L’udovít Klein—see the reference bout Gamrot vs. Klein—that showcased timing on level changes and safe pressure. Oliveira, meanwhile, is embracing the quick turnaround and the Rio spotlight. He publicly thanked fans and confirmed his target: a statement win to climb back toward gold.
What the switch means for the card
The Fiziev change also stirred interest among fellow Brazilians. Lightweight veteran Renato Moicano voiced his readiness, and featherweight star Diego Lopes—fresh off a big finish of Jean Silva (see Lopes vs. Silva)—rode a wave of fan calls too. The promotion ultimately locked in Gamrot, a move that preserves elite stakes and keeps the Brazilian legend in a five-round showcase.
Keys to victory
- Oliveira: establish the jab and body kicks early, force clinch breaks into knees and elbows, threaten fronts (guillotine, RNC) off Gamrot shots.
- Gamrot: win the entries with doubles and singles to outside trips, sit heavy in half-guard, avoid extended front-headlock exchanges, score mat returns.
