'Absolutely insane': UFC star stuns with never before seen KO

Welterweight Niko Price has stunned the world with a KO that has never been seen before in the UFC.

The 28-year-old star became the first fighter to knock out an opponent with hammer fists off his back at UFC Boise.

It’s just the second time any fighter has knocked their opponent out while in a bottom position.

The achievement is incredibly rare, due to the difficulty in generating power while lying down, with much of your body pinned.

However Price displayed his insane power by finishing the fight in the second round against Randy Brown from the position.

“I hooked it, I went to pass (the leg) over, I saw his chin, and I was like, ‘Let’s see what happens,’” Price said.

Fight fans took to Twitter to share their amazement at the finish.

In the main fight at UFC Boise, heavyweight Junior dos Santos beat Blagoy Ivanov by unanimous decision.

Meanwhile, Sage Northcutt earned the most impressive win of his career by knocking out Zak Ottow in the second round.
