Cody Stamann brought 15 UFC fights into a Muay Thai ring in Detroit last weekend, and Jake Peacock knocked him out.
Peacock, the former ONE Championship fighter who goes by “The One,” stopped Stamann in the main event of MMT11: MMA vs. Muay Thai in Detroit, Michigan. Jesse Holland of MMA Mania reported the result Monday with video of the finish. The clip had already been making the rounds on r/MMA, where a thread went up early Sunday and the fight earned a spot in the subreddit’s weekly highlights recap for Nov. 1 through Nov. 7. It sat in the same list as Waldo Cortes Acosta vs. Johnny Walker and Christian Lee vs. Tye Ruotolo.
Peacock is 33. He was born without his lower right arm because of complications during his mother’s pregnancy, and he has built his striking around that fact instead of in spite of it. He gloves the stump and uses it to hit people. Think about the problem that creates for an opponent. Every reference point a fighter has for reading a right hand, the shoulder turn, the distance, the angle, gets scrambled when the weapon coming at him is shorter than anything he has drilled against.
Holland framed Peacock as the man picking up where Nick Newell left off, and the comparison fits the trajectory. Since his ONE run, Peacock has been piling up wins on the local circuit, per MMA Mania. A UFC veteran at the top of the card was a different kind of test, and he talked about it that way afterward.
“Big respect for Cody, he’s accomplished so much,” Peacock said after the fight. “He’s been in there with absolute killers. Some of the best in the world, a ranked UFC fighter. So, my job was to get the job done quickly, not mess about. I wanted to take him out, make a point. There are levels to striking, There are levels in this sport, and I am the level up there.”
For Stamann, the loss is his first since he left the UFC in late 2024. He went to a new ruleset with a long Octagon résumé, and it didn’t carry over against a specialist who had clearly game-planned to end things early.
The reporting doesn’t include the round or time of the stoppage, and neither fighter has a next booking announced in the coverage so far.
My take: I love this fight for Peacock, and I’ll be honest about Stamann too. An MMA veteran crossing over to pure striking is betting that elite-level experience translates. Peacock told everyone his plan was to take Stamann out and prove a point about levels, and then he did exactly what he said. Respect to Stamann for taking the swing at a new sport, because plenty of ex-UFC guys would have picked a softer landing spot. He picked a guy who throws punches with a gloved stump and wanted the headline. Peacock got it, and now promoters with bigger budgets have a viral knockout of a 15-fight UFC name sitting on their phones.
