He's an unbeaten underground streetfighter that you guys have probably heard of. But for those of you who haven't here's an introduction to Kimbo Slice:

Kimbo is just a heavy handed street fighter whose promoters made great use of the internet to get his name out there. When big guys who know how to punch hit other guys bare fisted, the result is the damage you see in the video. It doesn't take a guy Kimbo's size to do that damage without gloves however. Jeff Lacy could inflict the same injuries on an untrained brawler.
Like he said, he was beaten by gannon awhile ago and then i think gannon whent to ufc and got hes ass beat aswell.
Yeh he got grounded and pounded into a stoppage. And in the underground fight Kimbo's team set all the rules i.e no taking it to the ground to suit him and he still got whooped
