MMA fighter pummelling KOed opponent on floor gets shock of his life

Frederick looked completely dominant as he sat aside opponent Ahmad Aswad, punching his prone body.

But umpire Leon Roberts proved you should never mess with a ref as he subdued Frederick with a choke hold in a split second.

Aswad seemed to be holding his own in the Fight UK: Last Man Standing lightweight bout.

But Brummie Frederick dodges Aswad's swings before catching him with a left hook.

Frederick dives on fallen Aswad and starts beating the living daylights out of him with his powerful right – refusing to stop even as Roberts tries to pull him off.

So Roberts takes matters into his own hands – literally – with a rear naked choke hold.

As the commentator says: "Anyone who says refs don't train: watch that."

Needless to say, Frederick was awarded the KO victory.
