Belfort KOs Rockhold

Back in 2013, Vitor Belfort stepped inside the Octagon to take on rising star Luke Rockhold in Brazil. Less than three minutes later, the former UFC champion had another highlight-reel finish.

Belfort landed a spinning heel-kick on the future UFC champion, finishing the fight as part of a three-fight win streak that earned him a shot at then-titleholder Chris Weidman.

Next weekend, Belfort returns to action, taking on Lyoto Machida at UFC 224.
