Charles Radtke Record: 12-5-0

UFC run

Radtke made his Octagon debut at UFC 293 in September 2023, edging Blood Diamond by unanimous decision over three rounds. He kept the momentum going in February 2024 with a first-round TKO of Gilbert Urbina. A grappling-match loss to Eryk Anders that spring was a different discipline, but his MMA progress hit a wall in June 2024 when the dangerous Carlos Prates stopped him with a first-round knee to the body.

To his credit, Radtke responded the way he always has – by swinging back. He bounced into the win column in November 2024 with a first-round TKO of Matthew Semelsberger in a fan-friendly brawl. He was knocked out by Mike Malott at UFC 315 in May 2025, then rebounded again in November 2025 with a third-round rear-naked choke of Daniel Frunza, showing off the grappling that started his whole career. He extended the streak in April 2026 with a unanimous-decision win over Francisco Prado at UFC 327.

Fighting style

Radtke is a well-rounded finisher who is most comfortable in a phone-booth firefight. His record splits cleanly – five wins by KO/TKO, three by submission and four by decision, a 67% finish rate – reflecting a fighter who can end a night with his hands or hunt the choke off his black-belt grappling base. He fights with a high pace and a willingness to trade, which produces highlight finishes but also leaves him in dangerous exchanges; both of his UFC defeats came by knockout, a sign that his durability gets tested when he stands and bangs with the division's biggest punchers.

Career highlights

• CFFC welterweight champion — captured a regional title with a first-round submission of a previously undefeated champion to earn his UFC call-up.
• Debut-night statement — beat Blood Diamond by decision at UFC 293, validating his late-career jump to the sport's top promotion.
• Resilient UFC run — repeatedly bounced back from losses, including a finish of Matthew Semelsberger and a submission of Daniel Frunza, showing the toughness that defines "Chuck Buffalo."
