Charles Radtke

Overview

Two of Charles Radtke's UFC losses came by knockout, two of his wins did too, and three of the four ended inside the first two rounds. Fights involving "Chuck Buffalo" rarely drift.

The Illinois-born welterweight fights out of Valley Flow Striking and sits at 5-2 in the UFC (12-5-0 across all promotions). He arrives at his next fight on a two-fight win streak.

A fighter who gets hit as often as he hits, and who has built a winning record anyway.

UFC Career

Radtke debuted at UFC 293 with a unanimous decision over Blood Diamond, going the full three rounds. Next came Gilbert Urbina in February 2024, a first-round knockout at 4:47.

Then the first setback. Carlos Prates stopped him in the first round at the same 4:47 mark that had ended Urbina's night. He rebounded in November 2024 with his fastest finish, a knockout of Matthew Semelsberger at 0:51 of round one.

The second loss was the harder one. Mike Malott, an opponent our model rates as strong, finished him in 26 seconds of round two at UFC 315.

Since then he has won twice. He submitted Daniel Frunza at 4:29 of round three, then took a unanimous decision from Francisco Prado at UFC 327.

The losses have been quick and the wins have come in every form.

Fighting Style

Charles Radtke is a wrestling-based fighter who takes opponents down far more often than most in the UFC. He rarely hunts for submissions, and his one submission win came late, in round three.

The striking is where the risk sits. He lands less than most fighters, takes a lot of punishment, and is hit more often than most. He also gets taken down more than most, even as he leans on his own takedowns.

His finishes tend to come early. Two of his three finishes were first-round knockouts, and both of his losses came by knockout.
