Joe Harding was squaring off Saturday against Johan Segas in the British MMA 18 featherweight title fight. Harding won the two opening rounds easily and was attempting to fire up the hometown crowd by breaking into the famous Muhammad Ali shuffle.

But he clearly underestimated Segas' quickness and was knocked out with a swift kick to the head. Segas then pounced on his fallen rival as the referee rushed in to stop the fight.

According to the Daily Mail, Harding was able to leave the ring under his own power.

He will likely think twice about channeling his inner Ali again, since the video of his humbling defeat has gone viral on social media in recent days.

"You don't do that kind of stuff," the announcer said on the broadcast after Segas scored the shocking KO.
