'Brocktober' continues tonight on Spike as Lesnar hits 'UFC 121 Primetime'

We get a look at the training, attitude and lives of both UFC heavyweight champ Brock Lesnar and challenger Cain Velasquez tonight on UFC 121 Primetime at 11 p.m. ET/PT. They meet in just over two weeks at UFC 121 in Anaheim.

Lesnar may be billed as an unstoppable force but it's clear that he's needs to restore much of that aura after he was beat up by Shane Carwin at UFC 116. Las Vegas bettors aren't buying the unbeatable label. Lesnar is a small favorite at minus-140.
