In a battle of undefeated heavyweights, Stipe Miocic showed he's a much, much brighter prospect than Philip De Fries. Miocic won by first-round knockout with brutal punches at Wednesday night's UFC on FUEL event in Omaha, Nebraska.

De Fries landed a looping overhand right at the start of the fight that briefly got Miocic's attention, but from there it was all Miocic: He landed a straight right hand to knock De Fries back, then knocked him down with another punch and finally pounced on top of him and landed more punches until the referee stepped in to stop the fight.

Miocic has been viewed as a promising heavyweight prospect for quite some time, and now he has finally delivered in the UFC, after a mediocre decision win over Joey Beltran in his UFC debut. By running his record to 8-0 in impressive fashion, Miocic showed just how lethal he can be with his punches.

As for De Fries, who falls to 8-1, he doesn't look like a UFC-quality fighter. He'll probably be one-and-done inside the Octagon.
