YouTube sensation signs with UFC to fight on Adelaide card

The UFC has signed an internet sensation after a video emerged of him knocking out a tattooed bully in 20 seconds.

Fighter Ben Nguyen, who emigrated to Australia two years ago, will feature in Adelaide’s UFC card in May this year.

The clip below shows the 26-year-old Nguyen at weigh-in for a fight and his tattooed up competitor pushing and shoving him.

The fight then begins and ends just as quick with Nguyen knocking out his opponent in 20 seconds.

The video has gone viral with the view count clicking well over seven million times since March.
