Watch Replay SILVA vs GRIFFIN in UFC 101

UFC middleweight champion Anderson Silva remained undefeated in the Octagon Saturday night, moving up to light heavyweight and destroying former champ Forrest Griffin, hardly even breaking a sweat before beating Griffin by first-round TKO.

After they felt each other out for the first couple of minutes, Silva landed a powerful right punch that leveled Griffin. He let Griffin up and leveled him again, then did it a third time before the referee stopped the fight.
