Recent Form
Avious Griffin (Coming off loss but previously dominant): The 31-year-old suffered his first defeat in June 2025, a dramatic 10th-round KO loss to Julian Rodriguez on a Jake Paul undercard after leading much of the fight. Prior, Griffin was on a tear with 10 straight stoppages, including an 8th-round TKO over Jose Luis Sanchez for a regional title (February 2025). Known for explosive power and aggressive style, he’s looking to rebound strongly.
Justin Cardona (On win streak): The 26-year-old has won recent bouts, maintaining activity with decisions and stoppages against regional opposition. His lone loss came earlier in his career; he’s shown improvement in volume and durability, often going deep in fights.

Key Fighter Matchups – Styles & Physical Advantages:
Height/Reach: Griffin (6’0″, reach unavailable but taller frame) holds a clear height edge over Cardona (5’8″, ~67″ reach), aiding jab control and power shots from distance.
Power vs. Chin: Griffin’s elite 94% KO rate (16 KOs in 17 wins) contrasts Cardona’s solid but lower finishing power; Cardona has proven durable, rarely overwhelmed.
Style Clash: Both orthodox. Griffin is a power-puncher with heavy hands, sharp combinations, and forward pressure—excels at breaking opponents down inside. Cardona brings high-volume punching, good movement, and body work, preferring to outwork foes over rounds. Expect Griffin to seek early openings for his power; Cardona to use footwork and activity to frustrate and extend.
Experience Edge: Griffin has more fights and faced slightly tougher recent opposition; Cardona’s youth and activity provide freshness.
X-Factor: Griffin’s rebound motivation post-KO loss vs. Cardona’s underdog hunger; big-stage exposure could favor the more experienced Griffin.
This is their first meeting—no prior fight history.
Betting Trends
Value on Under rounds and Griffin by KO, citing his high finishing rate (16/17 wins inside distance pre-loss) vs. Cardona’s mixed stoppage record. Public parlays heavily feature Griffin ML with main event and other undercard favorites; analogs to power vs. volume matchups favor Griffin early. Light action on Cardona for distance or upset, but low cash potential against Griffin’s resume.
