Stephen Thompson closed his career the way fighters dream about it: with a finish. The 43-year-old landed a spinning wheel kick midway through the third round on Saturday and knocked out Charles Radtke on the Polymarket UFC 334 prelims at Madison Square Garden.
The result mattered because Thompson, known as Wonderboy, did not simply leave on his feet. He left after taking a fight that had briefly gone against his style and then turning it into a sudden ending. Radtke used wrestling in the opening round to slow Thompson’s striking and keep the bout from becoming the kind of open, technical exchange that has defined much of his run.
Then the fight changed fast. Thompson found the one strike Radtke could not ride out, a spinning wheel kick that finished the bout at the two-minute mark of the third round. For a veteran whose name has long been tied to movement, timing and distance, the ending fit the career: patient, then explosive. It also gave the prelims a retirement moment that stood out on a card built around quick conclusions and hard decisions.
That was only part of the night. Chris Duncan beat Drew Dober by decision in a fight that earned Fight of the Night honors, while Terrance McKinney stopped Jim Miller in the first round and kept his 100-percent finishing rate intact. McKinney, known as T. Wrecks, said afterward that he is moving to welterweight after a bad weight miss on Friday, a shift that helps explain why his fight ended in five minutes or less for the ninth straight contest.
The contrast on the prelims was clear: Thompson survived the first-round wrestling test, then ended his own career with striking; McKinney kept finishing fights; and Duncan and Dober produced the kind of back-and-forth action that usually gets remembered long after the card is over. For Thompson, the unanswered question is not how the fight ended. It is why this was the one he chose to make his last.
