Carlos Diego Ferreira vs. Billy Quarantillo

OddsCarlos Diego Ferreira -191·Billy Quarantillo +158(DraftKings)
Neither of these men knows how to be in a boring fight, and both are at the stage where durability fades fast. Quarantillo's pace could absolutely break a 41-year-old Ferreira over three rounds, but his leaky defense has now produced stoppage losses in two straight, and Ferreira hits harder and has the far more dangerous ground game. Expect a wild, back-and-forth fight with both men hurt at some point. Ferreira by finish in the middle rounds, with a Quarantillo decision as the fallback if his engine holds up.
The Matchup
This is a crossroads fight between two beloved action fighters who are both on two-fight losing streaks and both closer to the end than the beginning. Quarantillo will do what he always does - march forward and drown opponents in volume - but his 43 percent striking defense means he gets hit constantly, and Ferreira still carries real power plus an elite submission game if it hits the floor. Ferreira, at 41 and coming off a knockout loss, has to weather the early pace and make his cleaner counters and grappling count. Quarantillo also hasn't fought in 20 months, which adds rust to the equation. Someone's skid ends, and someone's UFC future gets very cloudy.

The Numbers
Career UFC averages. Red bar = statistical edge.
Carlos Diego Ferreira
Carlos Diego Ferreira is a Brazilian jiu-jitsu black belt and former Legacy FC champion who has been a UFC lightweight since 2014, with wins over names like Anthony Pettis and Mateusz Rebecki on his resume. He blends slick submissions - seven career sub wins - with surprisingly heavy hands, as his ground-and-pound stoppage of Rebecki showed. Now 41, he is on a two-fight skid after losses to Grant Dawson and Alexander Hernandez. Fighting out of Pharr, Texas, he is deep in the twilight of a long career and likely fighting to extend it.

Billy Quarantillo
“Billy Q”
Billy Quarantillo is a Buffalo-born action fighter who earned his UFC deal through the Contender Series in 2019 and has been in wars ever since. His style never changes: relentless forward pressure and one of the highest strike outputs in the sport at over seven significant strikes landed per minute. That approach has produced 13 finishes in 18 wins - but also a lot of absorbed damage, and he enters on a two-fight skid after losses to Youssef Zalal and Cub Swanson. This is his first fight since December 2024 and his move up to lightweight, taking on Diego Ferreira at 37 years old.
