Charlie Radtke

Charles 'Chuck Buffalo' Radtke is a 35-year-old welterweight who took an unconventional path to the UFC. After spending 11 years climbing the regional and international circuit, he earned his Octagon debut in September 2023 with a win over Mike Diamond. His early UFC arc was turbulent: back-to-back knockout losses to Carlos Prates and Mike Malott in 2024 and early 2025 threatened to derail what many assumed would be a quick exit for a journeyman fighter in his mid-thirties. But Radtke recalibrated and found his rhythm again. A submission victory over Daniel Frunza in November 2025 and a dominant three-round decision over Francisco Prado in April 2026 have steadied his trajectory and suggested he remains a credible middleweight threat rather than a fading prospect.

Radtke's fighting style is built on explosive power and finishing instinct. He boasts five knockout wins and three submissions on his professional record, including five first-round finishes that underscore his preference for immediate aggression. His striking is sharp and heavy-handed, though his defensive metrics are thin (30% significant strike defense, suggesting he eats shots on his way in). He compensates with timing, power output, and an elite grappling background: he is a black belt in jiu-jitsu with a specialty in flying armbars and rear-naked chokes. When Radtke's explosiveness syncs with his opponent's openness, he is capable of jaw-dropping early finishes. When it does not, he can grind three rounds.

Off-cage, Radtke carries an uncommon personal narrative. He owned a bison ranch with his grandfather in Wisconsin before pursuing fighting to build confidence. That origin story, paired with his lengthy apprenticeship in smaller promotions and his current late-career resurgence, lends him a quiet, determined persona that resonates with fans who prize journeys over hype. He speaks thoughtfully in post-fight interviews about legacy and gratitude rather than callouts or trash talk. At 35 and 12-5, he is neither a title contender nor a gatekeeper, but a finisher who has earned a real UFC run after a lifetime of smaller shows.
