On Friday night, the main event of Bellator 138 featured Kimbo Slice taking on Ken Shamrock. This would have been a dream fight 6 years ago when it was originally supposed to take place. Instead we saw a fight in which a 51-year-old Shamrock didn't have the strength to put away the 41-year-old Slice when he got him into a choke hold. Once Slice was able to get out of the choke hold, both fighters got up, faced off and Slice landed some vicious bombs that knocked out Shamrock.

You can see the knockout at the 2:44 mark in the video above.
