The three swing fights (why they matter)

1) Charles Oliveira vs. Mateusz Gamrot — Lightweight (5 rounds)

Storyline: Oliveira got a new dance partner after Fiziev’s injury; Gamrot walks into a raucous Rio aiming to climb the ladder.
Tactical keys:

  • Oliveira: jab/teep to disrupt entries; low kicks to stall level changes; threaten front-headlock/guillotine on shots.

  • Gamrot: chain-wrestling, mat returns, and fence pressure to bank minutes.
    Telltale: more clean center exchanges → Oliveira’s pace; more wall time/positional control → Gamrot’s game.

2) Deiveson Figueiredo vs. Montel Jackson — Bantamweight (3 rounds)

Storyline: the ex-flyweight champ continues to settle at 135 against a tall, long opponent.
Tactical keys:

  • Deiveson: explosive counters; guillotine threat if Jackson level-changes sloppy.

  • Jackson: volume jab, check-hooks, and clinch rides to slow the fight.

3) Vicente Luque vs. Joel Álvarez — Welterweight

Storyline: pressure puncher vs. lanky technician with nasty knees and elbows.
Tactical keys:

  • Luque: cut the cage, hack the lead leg to trim reach.

  • Álvarez: knees on entries, tight elbows inside the clinch.

What to watch in the first 90 seconds (Oliveira vs. Gamrot)

  1. Center line: if Oliveira claims center early, Gamrot must shoot from farther away.

  2. First takedown layer: a sprawl + neck threat can cool the chain.

  3. Base checks: if low kicks land clean, Gamrot’s timing drifts half a beat.
