Cain Velasquez has finally avenged his UFC on FOX loss to Junior dos Santos, with a dominant performance during all five rounds at UFC 155.

The fight between Velasquez and dos Santos headlined the card, which took place at the MGM Grand Garden, Arena in Las Vegas, Nevada.

Velasquez opened by constantly pressuring dos Santos with takedown attempts and fundamental striking combinations. Despite the fact that Velasquez failed finish a takedown on JDS, he was relatively successful on his feet. Interestingly enough, the Brazilian looked very reluctant with his striking, allowing Velasquez to build-up his confidence.

The most important moment came towards the end of Round 1, when Cain Velasquez dropped dos Santos with a powerful right hand. The champ was dazed, with Velasquez swarming to get an early stoppage. Yet, JDS survived the onslaught, but was seriously wobbled once the referee Herb Dean signaled the fighters to get back to their corners.

From there, Cain Velasquez continued to dominate. JDS' hands were down, he looked slow and sluggish, and was taken down on numerous occasions.

Even so, dos Santos proved he's a great Mixed Martial Artist by not giving up, and trying to find his way back into the fight. He responded with good punching combinations, mainly to the body, and more of his legendary takedown defense.

Some would say that JDS scored a psychological victory by not getting knocked out or submitted by Cain Velasquez. However, the AKA product's relentlessness is the real headline of this fight. Cain Velasquez showed he's an A-class fighter, worthy of being the UFC Heavyweight champion.

Trilogy, anyone?
