A Spinning Kick to Say Goodbye: Stephen 'Wonderboy' Thompson Ends His Career With a Third-Round Knockout at the Garden

Some careers fade out. Stephen "Wonderboy" Thompson's ended with the move that made him famous. In his final fight Saturday night at Madison Square Garden, the 43-year-old karate stylist knocked out Charles Radtke with a spinning wheel kick to the head at 2:54 of the third round of their welterweight bout at UFC 334, ESPN reported.

It was the last chapter of a 16-year run in mixed martial arts, and it came after the hardest stretch of his career. Yahoo Sports noted the win snapped a three-fight losing streak, with defeats to Shavkat Rakhmonov, Joaquin Buckley and Gabriel Bonfim. Few fighters get to walk away on their own terms. Fewer still walk away with a finish like this one.

The fight did not start the way the Garden crowd wanted. According to Bloody Elbow, Radtke took Thompson down twice early, and fans who came to see one last display of the veteran's striking let their frustration be heard with boos. Thompson stayed patient, kept his distance and kept looking for his moment.

It arrived late in the final round. Thompson spun into a wheel kick that landed to Radtke's head, and the bout was waved off with a little more than two minutes left on the clock, ESPN and Yahoo Sports reported. For a fighter who built his name on kicks from angles opponents never saw coming, it was the perfect closing statement.

After the stoppage, the arena played a video tribute to Thompson's career. Bloody Elbow reported that Thompson became emotional as it ran, and so did his father, his coaches and longtime UFC commentator Joe Rogan. Speaking afterward, Thompson said he could not have asked for a better ending than a spinning kick after nearly 15 years with the promotion, according to ESPN.

Thompson twice fought for the UFC welterweight championship and spent years among the best 170-pound fighters in the world. His wide stance, quick feet and traditional karate base gave opponents a puzzle that many of them never solved.

What I will remember just as much is how he carried himself: respect for the people across the cage, gratitude toward the sport, and no trash talk for attention. Before the fight, he told Forbes that recovery between camps had become harder with age. He did not chase one more payday or one more ranking. He picked his night, prepared for it, and finished it.

There is a lesson in that for every young athlete watching. Scripture puts it plainly: "I have fought a good fight, I have finished my course." Finishing well is its own kind of victory, and on Saturday night Thompson got to do both: win, and leave.

Thompson's farewell came on a card billed as a title doubleheader and topped by Ciryl Gane's heavyweight championship defense against Josh Hokit, as Yahoo Sports' live coverage laid out.

Earlier in the evening, Kevin Holland and Uros Medic fought to a majority draw. Cageside Press reported the judges scored it 29-27, 28-28 and 28-28, a result shaped in part by a point taken from Medic in the second round for groin strikes. A draw satisfies almost no one, and both men left the cage without the win they came for.

Terrance McKinney, who missed weight for his bout and apologized for it this week, wasted little time once the fight began. He knocked out veteran Jim Miller at 1:53 of the first round, according to Yahoo Sports' live results. Miller, a longtime UFC veteran, had agreed to go ahead with the fight at a catchweight despite the miss, a decision that spoke well of his professionalism even on a hard night.

For Thompson, what comes next is time at home and whatever role he chooses in the sport he gave so much to. For the welterweight division, the loss of one of its most respected veterans leaves a gap that rankings alone will not fill. Radtke, on the wrong end of what will surely be one of the most replayed finishes of the year, will look to rebuild after a night that belonged to someone else.

In a sport that often rewards noise, Thompson built a following on skill and decency. He leaves the same way he arrived: light on his feet, calm under pressure and armed with a kick nobody saw coming.
