15-fight UFC veteran gets KO’d in one round by Muay Thai star who is missing an arm

Former UFC bantamweight Cody Stamann suffered a first-round knockout loss to limb-different fighter Jake Peacock in Detroit, Michigan. The bout took place at a Mitten Muay Thai event held at the Masonic Temple on November 7. Peacock quickly overwhelmed the 15-fight UFC veteran with a combination of punches, kicks, and elbows, marking the first knockout defeat of Stamann's professional combat sports career.

Peacock, a former ONE Championship competitor who was born missing an arm, secured his second consecutive victory since leaving the promotion. Stamann, who ended his near-decade stint with the UFC in 2024 following a loss to Da'Mon Blackshear, previously claimed a victory in MMA under Legends of Combat before making this unsuccessful transition to Muay Thai.
