Fighter Form & Recent Momentum

Regis “Rougarou” Prograis

Former WBA & WBC super lightweight champion

Coming off back-to-back losses:

UD loss to Devin Haney (Dec 2023)

UD loss to Jack Catterall (Oct 2024)

Prior wins include:

SD vs Danielito Zorrilla

TKO vs Jose Zepeda

TKO vs Tyrone McKenna

Prograis is known for his explosive power (83% KO rate) and aggressive pressure fighting. However, recent losses exposed defensive lapses and footwork issues.

Joseph “JoJo” Diaz

Former IBF super featherweight champion

Lost 6 of his last 7 fights, including:

SD loss to Abraham Montoya (Nov 2024)

KO loss to Oscar Duarte (Apr 2024)

SD loss to Jesus Perez Campos

Recent win: UD vs Jerry Perez (June 2025)

Diaz is a skilled technician with a high guard and solid body work, but his recent form suggests a decline in durability and confidence.

Style Matchup: Pressure vs Precision

This is a battle of two southpaws with contrasting strengths:

Prograis: Relentless pressure, stiff jab, and knockout power.

Diaz: High guard, body punching, and counterpunching ability.

Keys to Victory

For Prograis:

Apply early pressure and increase punch volume

Exploit Diaz’s tendency to shell up defensively

Target the guard with persistent combinations

For Diaz:

Attack the body to slow Prograis’ forward momentum

Capitalize on Prograis’ low guard with well-timed left hands

Show urgency from Round 1 to avoid being overwhelmed

What’s at Stake?

No title on the line, but this is a career-defining crossroads bout.

A win for Prograis keeps him in contention for another title shot.

A win for Diaz revives his career and proves he can still compete at 140 lbs.

A loss for either could signal a slide into gatekeeper status.
