UFC 155 Extended Video Preview: Dos Santos vs. Velasquez 2

A little over a week from now, two of mixed martial arts' most feared heavyweights will do battle as UFC champ Junior dos Santos faces former title holder Cain Velasquez for the second time at UFC 155.

This is a rematch of their epic UFC on Fox bout where "Cigano" emphatically took the belt from Velasquez with a devastating knockout just 64 seconds into the first round.

With both men emerging victorious from their respective recent fights, they are now once again set to face each other inside the Octagon as the world's largest MMA promotion ends the year with a bang.

Check out an extended preview of this epic rematch in the video embedded above.

Following their November 2011 fight, both dos Santos and Velasquez next fought at UFC 146. The Brazilian champ successfully defended his title with a brutal second-round finish of Frank Mir. Velasquez, meanwhile, rebounded from his first career loss by leaving Antonio Silva a bloody mess with a first-round TKO.

The victory, which earned the former champ another crack at dos Santos, is probably my choice for 2012's bloodiest finish. That cut on "Bigfoot's" head looked like the behemoth heavyweight got hit with an ax.

With the card also featuring a huge lightweight bout between grappling aces Jim Miller and Joe Lauzon as well as a host of heavy hitters such as Melvin Guillard, Todd Duffee and Chris Leben, from top to bottom, UFC 155 is a can't-miss event.
