UFC Sao Paulo recap: Who won the Vitor Belfort vs. Dan Henderson fight?

UFC middleweights Vitor Belfort and Dan Henderson squared off for the third time on Saturday night in the main event of UFC Fight Night: Sao Paulo. Belfort, a former light-heavyweight champion, proved that he is still a relevant fighter on the UFC roster with a first-round head kick knockout win over 'Hendo.'

Belfort and Henderson were both very tentative in the beginning, but things quickly changed when Belfort landed his signature head kick. The strike stunned Henderson, who dropped to the canvas and was clearly dazed. 'The Phenom' swarmed Henderson, following up with a few heavy bombs on the ground and referee Mario Yamasaki was forced to step in and bring an end to the proceedings.

Official Result: Vitor Belfort def. Dan Henderson via Knockout (Kick and Punches) at 2:07 of Round 1

What was the high point of the fight?

The high point of this fight was the only point of this fight. Unless you count Henderson's two leg kicks, literally nothing happened before the devastating head kick which ended the fight. Belfort just so happened to continue his trend of winning fights with a head kick, as he did so three times in 2013.

Where do these two go from here?

It would be interesting if Belfort decided to call it quits on a high note. He really doesn't have anything left to prove inside the Octagon, because it is unlikely that he'll make it back to a title shot anytime soon. If he keeps fighting, the idea of giving him "money fights" -- fights that aren't necessarily meaningful for the decision, but are exciting and will intrigue fans -- is an interesting one.

As for Henderson, he has to hang up his gloves and call it a career. His highlight reel and resume speak for themselves, but the 'H-Bombs' can't keep coming forever. The 45-year old is a shadow of his former self but for good reason. He was the last light-heavyweight Strikeforce champion and held two belts when he fought for PRIDE FC. He has nearly 50 fights under his belt, as well. Henderson is a future Hall of Famer, and he loves fighting. But everyone has to retire from the sport they love eventually, and Hendo's time is now.

Watch now, later, or never?

I think you can find just over three minutes out of your life right now to watch another devastating first-round knockout courtesy of Vitor Belfort.
