The welterweight clash was ended in the first round after Price pulled off one of the most ambitious moves in UFC history.
Price landed a one-two combination to start the fight before following that up with a kick to the face, which just missed.
However, Price was then taken to the canvas, as Vick looked to use the ground-and-pound.
At this point, Price launched his foot back before slamming his heel into Vick’s face.
Vick was immediately knocked out cold and fell flat onto Price, who kept punching him until he was pulled away by the referee.

Reports have suggested it was only the second time in UFC history a fighter has successfully used the upkick technique.
Speaking afterwards, Price sent out a warning to the rest of the UFC welterweight division.
“Wherever you’re at, I’ll hit you,” he said.
“I don’t care, fighting’s not a technique, just fight. Be a dog.”
UFC fans were stunned with the move and immediately took to Twitter to praise the victor.
One wrote: “Niko Price is amazing. He just did a horrible thing to James Vick, who has now lost 4-straight.
“NIKO PRICE MURKED HIM WITH AN UPKICK I’VE SEEN IT ALL” another tweeted.
One posted: “Niko Price with a brutal upkick, geez.”
“Niko Price is one of a kind, he really is,” another wrote.
“If that doesn’t win him a bonus I’ll fight Dana,” another joked.
