Rozenstruik’s UFC Career
Rozenstruik competed 15 times in the UFC from February 2019 to February 2025. He quickly made a name for himself with devastating knockout power and impressive athleticism.
The heavyweight fighter started his UFC run with three straight knockout victories. He headlined his first UFC Fight Night card against legendary fighter Alistair Overeem in December 2019.
Despite trailing on the scorecards, Rozenstruik landed a brutal knockout in the final seconds that split Overeem’s lip in gruesome fashion. The comeback victory established him as a dangerous contender in the division.
His next major test came against Francis Ngannou in a highly anticipated main event. The fight ended quickly with Ngannou knocking out Rozenstruik in just 20 seconds.
Rozenstruik remained a top-10 heavyweight for most of his UFC career. He scored impressive wins over former champions Andrei Arlovski and Junior dos Santos during his six-year run with the promotion.
He headlined six UFC Fight Night cards total and earned three post-fight bonus awards. Rozenstruik finished his UFC career with a 9-6 record.
Life After the UFC
The UFC released Rozenstruik in February 2025 following a decision loss to Sergei Pavlovich. The release came despite Rozenstruik holding a 2-1 record in his final three UFC bouts.
After leaving the promotion, Rozenstruik signed with Mike Perry’s Dirty Boxing Championship. He fought twice under the Dirty Boxing banner in 2025 and won both contests.
In his second fight with the promotion, Rozenstruik captured the inaugural Dirty Boxing heavyweight championship. He went 2-0 overall with the organization before his arrest.
The Pembroke Pines Police Department has not released additional details about the circumstances surrounding Rozenstruik’s arrest. Court records list both charges as domestic violence offenses.
