A shocking video has emerged as boxer Adrien Broner knocks a civilian out cleanly with a bare knuckle punch on the Las Vegas strip.

Bad news seems to follow former world champion Adrien Broner around everywhere these days.

The Ohio native was in Las Vegas recently and a truly incredible video has now emerged appearing to show Broner on a rampage in Sin City, at one point shoving a woman away – and then unleashing a devastating one punch knockout on a man shown out for the count.

The sound of the punch can be heard cracking off his skull.

The folks at TMZ (hat tip) captured the moment here as Adrien Broner knocks out a man in the street after also appearing to shove a woman:

Broner has had multiple brushes with the law in recent years and has seen a pro boxing career that has promised so much since he initially burst onto the scene and won world titles – going from the top of the mountain to now totally out of sorts.

Since 2013 Broner has suffered three defeats in his pro career and has also experienced large periods of inactivity due to outside the ring issues.

His last fight came back on July 29th when he dropped a unanimous points decision to Mikey Garcia. Broner’s current professional boxing record stands at 33-3-24KO at this time.
