Kimbo Slice’s son scores brutal first round KO in his MMA debut (Pics)

Kimbo Slice is probably the world’s most famous street fighter.

The 42-year-old made his name knocking people out for fun in back yard brawls which went viral on YouTube.

The hammer-fisted heavyweight then took his game inside the cage and has become a relatively big name in MMA.

Nearly 3 million people tuned in to see his fight against Dada 5000 at Bellator 149 (although the fight ended controversially with his opponent hospitalised after his heart stopped).

But it turns out Kimbo’s son Kevin Ferguson Jr has now followed his old man into the fight game.

‘Baby Slice’ made his MMA debut against Tom Brinks on the Warrior Nation: XFA XII show, according to MMA Fighting.

He didn’t disappoint either. Slice Jr, who was fighting at 175lbs, finished the fight with his fists after just 1:23 of the first round, scoring a TKO over Brinks with his superior stand-up.

Kimbo wasn’t there to see his son’s first ever MMA victory. But his son’s manager Mike Imber said “he’s got a bright future.”

All eyes will no doubt be on the 23-year-old Slice to see if he can really make it big in the game. Check out the photos here.
