Etim hit Faaloloto with a couple of punches early, then as Faaloloto went low to attempt a takedown, Etim sunk in a guillotine choke and wrapped Faaloloto up while they were still standing. Faaloloto attempted to slam Etim down, but that only allowed Etim to sink the choke in tighter, and Faaloloto had to tap.
The entire fight lasted just 17 seconds.
Etim, who has been sidelined for more than a year and a half with injuries, said afterward that he was motivated to get his career back on track.
"I think that's what 19 months off does. I was so hungry to get back in," he said. "It's absolutely killed me but I'm back now and ready to make an impact in this lightweight division. Let's do this."
Etim did it in a big way to get the UFC 138 broadcast started right.
