Early Career
Matthew Semelsberger was born and raised in Maryland, where his passion for combat sports ignited early. He began training in mixed martial arts at the age of 14, inspired by legends like Chuck Liddell and Forrest Griffin.
Before fully committing to fighting, he was a standout athlete in other arenas, notably playing Division I college football as a safety for Marist College. His athletic background provided him with the explosive power and discipline that would later define his fighting style.
After college, Semelsberger focused entirely on MMA, cutting his teeth in the regional circuits of the East Coast. He competed in promotions like Cagezilla and Triton Fights (formerly KTFO), where he captured light heavyweight titles.
His amateur and early professional career was marked by a willingness to take tough fights and a knack for finishing opponents, earning him a reputation as a dangerous striker. This regional success eventually caught the attention of the UFC in 2020.
Professional Career
Semelsberger made his UFC debut in August 2020, winning a unanimous decision against Carlton Minus. He quickly made headlines in March 2021 with a spectacular 16-second knockout of Jason Witt, earning a “Performance of the Night” bonus.

This victory showcased his devastating one-punch power and put the division on notice. He followed this up with another highlight-reel finish against Martin Sano later that year, needing only 15 seconds to secure the KO.
However, consistency became a hurdle as he faced stiffer competition. While he secured notable wins against fighters like A.J. Fletcher and Jake Matthews, he also suffered tough losses to veterans like Khaos Williams and Kevin Holland.
After a difficult stretch from 2023 to 2024, where he lost four consecutive fights, including a knockout loss to Charles Radtke in November 2024, Semelsberger was released from the UFC in early 2025.
Despite this setback, he remains a free agent with potential to rebuild his career in promotions like PFL or Bare Knuckle Fighting Championship (BKFC).
