Stephen Thompson concluded his professional career with a stunning performance at UFC 334, held at Madison Square Garden in New York City. The 43 year old fighter, widely known by his nickname Wonderboy, secured a victory through a spinning back hook kick in the third round. This final bout served as a poetic bookend to a career that began with significant moments in the same arena ten years prior.
Thompson had explicitly stated that this contest would be his last. The promotion did not offer him an easy opponent. Instead, they paired him with Charles Radtke, a resilient fighter whose only losses to ranked opponents had come against Joaquin Buckley and Mike Malott. Radtke embraced the underdog role, utilizing his wrestling abilities to control the early stages of the fight. He successfully barreled Thompson over and dictated the pace during the first round.
However, as the contest progressed, Radtke's stamina began to diminish. Thompson capitalized on this shift in energy, finding his rhythm in the second round. He utilized his trademark karate style, moving fluidly and delivering flicked combinations that began to take a toll on his opponent. By the end of the second round, Thompson had clearly hurt Radtke, setting the stage for a dramatic finish.
In the third round, Thompson delivered the decisive blow. He connected with a powerful spinning back hook kick that sent Radtke to the canvas, securing the knockout victory. The finish was widely regarded as a quintessential Wonderboy moment, potentially the most impressive knockout of his UFC career since his debut in 2012.
During the post fight interview, Thompson reflected on his long tenure with the organization. He told UFC commentator Joe Rogan, I've been with the UFC for almost 15 years. Tonight, I couldn't have done better than to go out with a spinning hook kick to the dome. The sentiment highlighted his desire to leave a lasting impression on fans and the sport.
The retirement of Thompson marks the end of an era for the welterweight division. Throughout his career, he spent the majority of his time ranked among the best fighters in the weight class. His journey included two challenges for the UFC welterweight title and bouts against four different UFC champions. His ability to compete at the highest level for so many years cemented his status as a legend.
Standing in his corner for this final fight was his father, Ray Thompson. The presence of family added a personal layer to the event, underscoring the support system that helped sustain Thompson through nearly two decades in the octagon. The crowd at Madison Square Garden witnessed a fighter who had consistently delivered high quality entertainment.
Thompson was remembered not only for his technical skill but also for his character. In a sport often defined by aggressive personalities and dramatic rivalries, Thompson maintained a reputation as the ultimate nice guy. His conduct both inside and outside the cage earned him respect from peers, opponents, and fans alike.
The fight at UFC 334 provided a fitting finale to a remarkable journey. From the thrilling matchup against Tyron Woodley at UFC 205, which was part of the promotion's big debut in New York City under the headline of Conor McGregor, to this final chapter, Thompson's career was defined by memorable moments under the bright lights of the Garden.
As he steps away from the sport, Thompson leaves behind a legacy of technical excellence and sportsmanship. His final victory, achieved through one of the most spectacular strikes in the division, ensures that his name will remain synonymous with the exciting, high flying style that made him a fan favorite.
