Charlie Radtke

Chuck Buffalo

USA

Finished by Mike Malott
WelterweightUFC
May 10, 2025
Radtke lost to Mike Malott via KO (punches) at 0:26 of Round 2 at UFC 315 on Saturday in Montreal.
ANALYSIS
Radtke is a tough guy and has shown a willingness to engage with his opposition in the past, but his biggest flaw has been a lack of durability at times, and we saw that again here. He dropped Round 1 to Malott, but was by no means overwhelmed. That all changed early in Round 2 when one straight left and some follow-up blows ended things in an instant. "Chuck Buffalo" has very little upside at age 34, but he's 3-2 since his September 2023 debut and makes for decent roster depth.

Destroys Matthew Semelsberger
WelterweightUFC
November 9, 2024
Radtke defeated Matthew Semelsberger via TKO (punches) at 0:51 of Round 1 at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Radtke displayed big power at times during his run on the regional scene and it's nice to see that carrying over to the UFC. Semelsberger has major durability issues, but Radtke was easily able to put him away with a quick one-two combination. "Chuck Buffalo" has minimal experience for a guy that turned 34 years of age in July, but he's already 3-1 in the UFC and his lone defeat came to an high-end opponent in Carlos Prates. Radtke's roster spot is plenty secure, even if his long-term upside appears pretty limited.

June 8, 2024
Radtke lost to Carlos Prates via KO (knee) at 4:47 of Round 1 at UFC Fight Night on Saturday in Louisville, Kentucky.
ANALYSIS
Things came crashing down here on Radtke, and it happened in a hurry. There wasn't a whole heck of a lot going on in Round 1, at which point "Chuck Buffalo" got clipped with a crushing knee to the gut which finished him in an instant. Prates walked away immediately knowing the fight was done, but it still took referee Blake Grice a few seconds to comprehend what had happened. Radtke began his UFC run with back-to-back wins over Blood Diamond and Gilbert Urbina, but things predictably got more difficult as the competition level was raised. The 33-year-old Illinois native is nothing more than roster depth.
