WATCH: Francis Ngannou Knocks Out Jairzinho Rozenstruik In 20 Seconds

It only took Francis Ngannou 20 seconds and a vicious hit to finish Jairzinho Rozenstruik in their heavyweight fight at UFC 249, Saturday night. The Surinamese mixed martial artist is fresh off an impressive come-from-behind victory against Alistair Overeem at UFC on ESPN 7 last December. It was his 10 straight win on his professional MMA career, four under the UFC banner, which sets him up to a titanic clash with his fellow knockout sensation. Ngannou, who previously fought for the heavyweight title, is currently riding a three-fight winning streak since his back-to-back losses to Derrick Lewis and Stipe Miocic. Going into this fight, 'The Predator' has been in one of the longest training camps of his career in what he described as "not the best conditions that you would like to be in." But eager to earn another shot at the heavyweight strap, Ngannou overcame the challenge as he aims to finish Rozenstruik. https://twitter.com/ufc/status/1258763060271087617

Insane Finish

The 31-year old completed his mission and sent 'Big Boy' to the shadow realm with solid strikes to wrap up the fight just 20 seconds into the opening round. "I was expecting this fight to be for the title," Ngannou said following the massive knockout win.
