'They don't get much cleaner than that'

Josh Emmett marked his return to the UFC featherweight division with one of the cleanest KOs of the year.

The American was a massive underdog against third-ranked featherweight Ricardo Lamas at UFC on Fox 26 in Winnipeg, Canada.

But Emmett made a mockery of his status with a brutal exhibition of power-punching against his compatriot.

The fight was evenly poised in the opening round when Lamas looked to land a big right on his opponent.

Emmett saw it coming though and evaded the punch before swivelling on the spot and hammering Lamas with a vicious left hook that sent him crashing to the canvas.

The shot was so clean and powerful that Emmett didn't even need to follow it up as Lamas lay sprawled on the canvas.

"I said that if I land one clean shot that I'll end the fight," Emmett said after the fight.

"Everyone was counting me out, and I guess I finally landed one clean shot.

"My goal was to come out here and shock the work. I think I might have."
