Stephen Thompson ended his MMA career on a high note earlier tonight (Saturday, November 14, 2026) at UFC 334 LIVE on Paramount+ at Madison Square Garden in New York City, when “Wonderboy” destroyed fellow welterweight Charles Radtke with a devastating third-round TKO (spinning wheel kick).
Despite his UFC experience, Thompson was only a slight betting favorite over Radtke in the “Prelims” headliner. That’s because Thompson is 43 years old and hasn’t looked quite like himself in a few years. Saturday was his official retirement fight, but a dangerous one. Radtke is a strong fighter at 170 pounds and trains with former UFC champion Belal Muhammad, who has a career win over “Wonderboy.”
Radtke did what most expected early on when he scored a matchup and level change to take Thompson down. Thompson is notoriously one of the hardest welterweights to pin down, so Radtke had to fight hard to get his positions. That only lasted until Thompson found his groove in the second round with a left hand followed by a combination that backed Radtke up against the cage and forced a takedown. Thompson defended and moments later landed a nasty toe kick to the body. Radtke was hurt, but the end of the round saved him.
Thompson continued his efforts early in the third round, landing a head kick that sent the MSG crowd roaring. Radtke lived for a few more minutes before Thompson unleashed a ridiculous spinning wheel kick. It fell on the side of Radtke’s head, and that was all he wrote. It was an incredible send off for one of the best strikers UFC fans have ever seen.
