Overview
- Stephen Thompson ended his UFC career with a spinning wheel kick knockout of Charles Radtke at 2:54 of round three at Madison Square Garden on November 14, 2026.
- Thompson had announced UFC 334 would be his final fight and publicly laid his gloves down in the Octagon to confirm his retirement after the win.
- Radtke used repeated takedowns and top pressure early in the bout but Thompson regained striking range and finished the fight with a high spinning back/wheel kick.
- Thompson said harder recovery with age, accumulated injuries, and the birth of his daughter drove his decision to retire and some outlets show minor differences in his final pro record.
- Thompson leaves a 14‑ to 15‑year UFC run as a two‑time welterweight title challenger and noted striker who may pursue lower‑risk striking work while prioritizing long‑term health and family time.
