Stamann Knocked Out By One-Armed Fighter In Muay Thai Debut

Former UFC bantamweight Cody Stamann dropped his Muay Thai debut in brutal fashion last weekend, stopped by Jake Peacock at MMT11 in Detroit. Peacock was born without a lower right arm but has turned that into an unconventional weapon, gliding the stump and deploying it as part of his striking game.

The 33-year-old Peacock, a former ONE Championship competitor, landed clean before finishing Stamann in a performance that showcased the gap between disciplines. Stamann logged 15 UFC bouts before leaving the promotion in late 2024, facing ranked opponents throughout his bantamweight run.

Peacock Credits Experience Gap After Finish

Speaking after the stoppage, Peacock acknowledged Stamann's pedigree while asserting his own superiority in pure striking. "There are levels to striking," Peacock told reporters, per MMA Mania. The victor noted Stamann had competed against elite competition during his UFC tenure but framed the result as proof of his own advantage in a Muay Thai setting.

The defeat represents Stamann's first loss since exiting the UFC and his initial foray into traditional Muay Thai competition. Peacock has carved a niche on the regional scene, following a path similar to Nick Newell, another one-armed fighter who overcame his physical difference to succeed in MMA.

Peacock's knockout extends his momentum in combat sports as he builds a resume outside traditional MMA promotions.
