Vitor Belfort gave Jon Jones a bit tougher of a challenge than many expected at UFC 152. It's not so much that Vitor did a lot, but rather that he had a single moment where he locked in an armbar that was very deep and looked to have done some real damage to Jones' arm.
Following surviving that armbar, Jones won basically every moment of the rest of the fight. Vitor found himself trying to pull guard and make lightning strike twice, but couldn't do it and Jones just dominated on the feet before getting on top and locking up an Americana to win the fight in round four.
Here are the highlights of the bout:
And here's how Bloody Elbow called that last round:
Round 4 - Vitor with a head kick and now he flurries with some uppercuts. Jones gets the takedown and Jones is on top and has an arm pinned, Jones locks in a kimura and that's that. Jon Jones wins by submission (kimura), round 4.
