Overview
- Thompson delivered a spinning hook/wheel kick that knocked out Charles Radtke in the third round and then placed his gloves in the center of the Octagon to signal his retirement.
- He had framed the matchup as his final fight and the win ends a three‑fight losing stretch while leaving him with an 18‑9‑1 professional MMA record.
- The post‑fight interview and video tribute drew strong emotion from commentators and teammates, with Joe Rogan visibly moved during the on‑air exchange.
- UFC president Dana White said he would test Thompson for a possible broadcast role, and Thompson received a $100,000 Performance of the Night bonus for the finish.
- Thompson built his reputation as a karate‑based striker after starting kickboxing in 1999, debuting in the UFC in 2012, and challenging twice for the welterweight title, and he now plans to teach and consider lower‑risk striking competition.
