The final UFC event of 2012 goes down tonight in UFC 155: Dos Santos vs. Velasquez 2. In the PPV main event Junior dos Santos has the chance to tie the UFC record for successful heavyweight title defenses. To do that he'll have to once again beat Cain Velasquez, who he took the belt from. The two first met at UFC On Fox 1 where JDS knocked Cain out cold in only 69 seconds. Both fighters were suffering knee injuries in that bout, so they're gonna do it tonight to settle the score.
In the co-main event, Lightweights Jim Miller and Joe Lauzon will meet in the Octagon. Both 155 lb. fighters are on the cusp of getting back to the top of the division. A win for either man should put them right back in Dana White's infamous "mix".
