- Bellator MMA has released a full preview documentary for the huge Ken Shamrock vs. Kimbo Slice main event that headlines this Friday's Bellator 138 show on Spike TV.

The documentary goes all the way back to 2008 when the two were originally set to face off, before a cut would force Shamrock to be pulled from the fight. He was replaced by Seth Petruzelli, who would go on to shock the world and knock Kimbo out, effectively killing the EliteXC brand. You can watch the full video preview above.

- Bellator has done its best to stack the Bellator 138 show with a strong undercard as well. Underneath the main event, the show also features former Bellator Champions Daniel Straus and Michael Chandler. Both are looking for big wins to get them closer to the title picture again.

- In addition to Kimbo Slice and Ken Shamrock's preview video, Bellator MMA has also released a brief interview segment featuring former TNA World Champion Bobby Lashley. Lashley is shown missing one of his front teeth as he promotes his fight for this Friday's event. You can see the video below.
