Jim Miller entered the Octagon at UFC 168 a -380 favorite against Fabrício Camões due to his impressive all-around skills. But he would end up defeating the Brazilian jiu-jitsu standout at his own game, nimbly rolling to an armbar from the guard to score an early victory tonight at the MGM Grand in Las Vegas, Nevada.

Camões, of Rio but fighting out of San Diego, CA, holds a third degree black belt in Brazilian jiu-jitsu and was cornered by his longtime Gracie Humaita coach, Royler Gracie. The Brazilian surprised many observers, landing a few good punching combinations and a takedown on Miller, a longtime UFC lightweight contender from New Jersey. Miller would then secure the armbar at 3:42 of that first stanza.

“You’ve seen Mr. Hyde, but I tried to bring Dr. Jekyll out today, and he’s a monster too,” Miller joked after the victory.

Miller’s victory was a rebound from a tough night against Pat Healy at UFC 159, where he fell to defeat after being caught in a choke. That bout that was later changed to a no-contest due to Healy’s failed drug test (for marijuana).

At UFC 168, Jim Miller defeats Fabrício Camões by submission (armbar) at 3:42 of round one.
