UFC on FOX Preview: Cain Velasquez Will Defend Title Tonight with Knockout Win

Tonight at 9 p.m. ET, UFC on FOX will kick off their first ever main event with Cain Velasquez (9-0) defending his heavyweight championship against Junior dos Santos (13-1) in what many expect to be the most exciting UFC championship fight in some time.

The two heavyweights are known for standing toe to toe in the cage and demonstrating their brute force.

Out of Velasquez's nine wins, eight have come by way of knockout.

Out of Santos' 13 wins, eight have come by way of knockout.

Right now it appears that their is nobody that can stand in the way of Velasquez. Just a few weeks ago he won the heavyweight belt from Brock Lesnar after a first-round knockout.

His only fight that went the distance was against Cheick Kongo.

On paper, Junior dos Santos may have the more impressive looking resume with 13 wins and just one loss, but he hasn't faced the same type of competition as Velasquez.

His most difficult fight came in June when he beat Shane Carwin by unanimous decision.

Not to undermine Carwin, but he isn't even close to being the same type of talent that the current champion is.

Velasquez doesn't let fights go the distance. Tonight won't be any different.

Look for Santos to go down some time in the second or third round in the first ever showing of UFC on FOX.
