In a stunning upset, Kimbo Slice was TKO'd in 14 seconds Saturday night by Seth Petruzelli.

Slice was knocked to the ground immediately after taking a button punch to the jaw. Petruzelli then followed with a series of punches to the face.

Seeing that Slice was defenseless, referee Troy Waugh jumped in and stopped the fight.

Petruzelli was a last minute replacement for Ken Shamrock, who suffered a cut around his left eye during a workout session.

Outweighed and outmatched, the no-name Petruzelli stunned the sellout crowd and handed Slice the first defeat of his MMA career.
