Francis Ngannou delivered some spectacular knockouts during his UFC career, but none of his opponents fell faster than Jairzinho Rozenstruik.
In May 2020, Ngannou needed just 20 seconds to defeat Rozenstruik. In reality, ‘Bigi Boi’ was out well before the official stoppage.
Ngannou knocked him out with a wild left hook, and the fight was over.
After rebounding from back-to-back decision defeats by knocking out Cain Velasquez, Curtis Blaydes, and Junior dos Santos, Ngannou was booked in a title eliminator bout against the undefeated prospect, Rozenstruik.
Rozenstruik had quickly earned a 10-0 record after transitioning to MMA from kickboxing and was fresh off a brutal fifth-round stoppage win over Alistair Overeem, whose lip seemed to explode during their fight in December 2019.
Several months later, he found himself standing opposite Ngannou.
Rozenstruik landed an inside leg kick to start the fight, but Ngannou used his noticeable size advantage to square up and charge at his opponent.
The Cameroonian fighter threw a series of shots until a left hook caught Rozenstruik flush on the jaw and sent him to sleep against the cage.
Rather than back away from his unconscious rival, ‘The Predator’ lived up to his nickname by landing several unnecessary shots.
Rozenstruik’s head bounced off the fence as Ngannou uncorked five follow-up hooks before veteran referee Dan Miragliotta was able to step in.
Boxing legend Mike Tyson was one of the many people watching who were blown away by Ngannou’s brutally quick finish of Rozenstruik.
Tyson made a bold post-fight prediction, stating on Instagram: “Resounding…vicious…future champ. Francis Ngannou 20 second knockout tonight.”
The 57-year-old Tyson had made a career by destroying opponents during his reign of terror in the 1980s, leaving many top heavyweight contenders on the floor.
Growing up as a child, Ngannou was a huge fan of ‘Iron Mike’ and wanted to emulate his career inside the boxing ring.
The two men came together to train ahead of Ngannou’s debut in the sport against WBC heavyweight champion Tyson Fury last October.
