Stephen "Wonderboy" Thompson ended his career at UFC 334 with a spinning back kick knockout over Charles Radtke, finishing the fight at 2:54 of the third round. The bout was held at Madison Square Garden, the same venue where Thompson fought at UFC 205 a decade earlier, when he drew with UFC welterweight champion Tyron Woodley in a headline-level debut for the promotion in New York City.

Thompson, 43, had announced beforehand that Saturday's bout would be his last. The promotion paired him with Charles Radtke, who had lost only to ranked opponents Joaquin Buckley and Mike Malott. Radtke opened aggressively, diving for a takedown before the first minute expired and holding Thompson against the cage for stretches of the first round. Thompson worked his way back to his feet and began establishing his jab and counter-fighting from range.S1S2

Thompson found more success in the second round, flicking combinations and mixing in straight punches and kicks as Radtke, who shot in for a takedown that Thompson resisted, began to tire. Thompson hurt Radtke at the end of the round and, early in the third, landed a heel kick to the face before unleashing the spinning back kick that sent Radtke to the canvas for the final time.S1S2

Thompson, who had been with the UFC for almost 15 years, said in his post-fight interview with Joe Rogan that he could not have asked for a better way to go out. He celebrated by laying his gloves down in the octagon for the last time. He ends his career having challenged for the UFC welterweight title twice and fought four UFC champions, and is widely regarded as one of the most lethal strikers in the promotion's history.S1S2
