10 Most Brutal Knockouts In UFC History

6. UFC 126: Anderson Silva Vs. Vitor Belfort

While Anderson Silva is featured elsewhere on the list for getting knocked out by Chris Weidman, here we see just how clinical The Spider was when on offense.

Back at UFC 126, Silva was at his best as he defeated fellow Brazilian legend Vitor Belfort.

The end of the fight saw Silva level The Phenom with a front kick that left his opponent a broken man. Belfort had no idea where he was, Silva had yet another big-name victim on his ever-expanding list of victories, and yet again the MMA world was left in awe at just how unstoppable Anderson Silva was.

It would be another 2 1/2 years after this fight that Anderson was finally defeated.
