Stephen Thompson vs. Charles Radtke Fight Preview
Stephen Thompson

- 8–2 (T)KO
- 1–1 SUB
Stephen Thompson is hanging up the gloves on Saturday night, looking to punctuate his career with a victory at Madison Square Garden. It’ll be easier said than done; at 43, he’s the oldest fighter on the active roster. The former title challenger has also dropped five of his last six fights — two by stoppage — and has been out of action for 16 months.
That said, all of Thompson’s losses during that stretch came against elite competition, including eventual welterweight champion Belal Muhammad and the undefeated Shavkat Rakhmonov. But for his retirement fight, “Wonderboy” draws a much friendlier — albeit still formidable — matchup against Charles Radtke. While Thompson has been vulnerable against grapplers in the past, he is characteristically hard to keep down. If he can thwart Radtke’s offensive wrestling, he can impose his signature, high-level karate striking one last time.

Still searching for a statement win inside the Octagon, Charles Radtke heads to New York City to spoil the retirement fight of a UFC fan favorite. The 36-year-old veteran has bulldozed his last two opponents with his impressive wrestling. Over the last year, he submitted Daniel Frunza in the third round before scoring a 30–26 decision win over Francisco Prado, racking up significant control time in both bouts.
“Chuck Buffalo” will likely attempt to follow a similar blueprint against a prolific striker in Stephen Thompson. However, Radtke has struggled to impose his will against strong competition. His last three wins have been against opponents coming off at least one loss, and he’s gotten knocked out by both Carlos Prates (June 2024) and Mike Malott (May 2025). While Thompson isn’t quite at that level anymore, he’ll mark another uphill battle for Radtke as he tries to prove himself in the UFC.
Stephen Thompson vs. Charles Radtke Pick, Best Bet
The biggest question heading into Stephen Thompson’s retirement fight is how his grappling will hold up at 43, after so much time away. If he can disrupt Charles Radtke’s offensive wrestling, “Wonderboy” can show off his clear advantage on the feet, bolstered by a considerable size advantage. Given Radtke’s compromised chin, a knockout victory could be within reach. But if Thompson’s grappling doesn’t endure, there’s a legitimate chance that Radtke ragdolls the Hall of Fame candidate like his last two opponents, potentially cinching a submission victory. Either way, it seems unlikely that Thompson’s curtain call goes the distance.
