Terrifying MMA powerhouse Francis Ngannou took UFC 218 by storm in his pay-per-view debut with a jaw-shattering uppercut to knockout heavyweight great Alistair Overeem.

NowNgannou has been confirmed to fight heavyweight champion Stipe Miocic at UFC 220 on Jan. 20, 2018, according to MMAFighting.com.

The UFC world was in awe of the 31-year-oldNgannous brutal power after clocking Overeem, one of the most well-rounded heavyweights in the competition, on the chin to send him to the canvas like a rag doll.

Commentator Joe Rogan said the main card fight was like a scene from a movie as UFC stars around the globe tweeted about the blockbuster finish.

Im not sure if Ive ever seen a humans head snap back like that, featherweight Dennis Bermudez tweeted.

Scary, scary power, added former lightweight contender Kenny Florian. Nobody at heavyweight wants to get hit by that cinder block fist.

Flyweight Ray Borg feared for the entire roster.

Thats it, Ngannou can no longer fight humans, he said. Its not fair and someone might die.

Fans of the Cameroon-born star, who has an inspiring rags-to-riches story, only need to wait a few more weeks to see him back in the Octagon.

Ngannou has won all six of his fights in the UFC by stoppage, but Miocic has a five-fightstreak of his own including a run of four first-round finishes against Andrei Arlovski, Fabricio Werdum, Overeem and Junior dos Santos.

Now theyve got a star, Joe Rogan said after the weekends madness. I think Ngannou, one or two more fights, youre going to be looking at Mike Tyson days. Thats what I think. Youre going to watch fights just to see how long these motherfs can survive against this guy. Thats what I think. That could be their big, breakout star.

Meanwhile, interim middleweight champion Robert Whittaker has found himself in a mess after an illness relegated champion Georges St-Pierre to the sidelines.

Middleweight fighter Luke Rockhold doubted St-Pierre would ever defend his new title, and took aim at the confusion surrounding the middleweight title.

Wheres the clarity in the division? he said on MMA Hour this week. I did say that if he (GSP) did win, he wouldnt fight any one of us and wed just be more tangled up.

(Hes) backtracking on all these other levels. Its clear as day, hes not fighting. Hes not fighting any of us. Hes too small. Guys like me will feast on Georges. He wont last here.

He had his opportunity, he got his belt, good for you. Move along. Let us handle our business here. Im ready to fight somebody that makes sense and right now nothing makes sense.
