🚨 Anderson Silva's Foot Speed Takes Center Stage in Latest MMA Showcases

Marcus Aurelio put together a rather unmemorable tenure in the Ultimate Fighting Championship , save for one particular appearance on the outskirts of The Mile High City. The Pride Fighting Championships vet carved out a place for himself in the record books when he turned back Ryan Roberts with an armbar in the first round of their UFC Fight Night 13 lightweight prelim on April 2, 2008 at the Broomfield Event Center in Broomfield, Colorado. Their brief confrontation concluded 16 seconds into Round 1.

Aurelio stepped forward behind his jab, floored the former Victory Fighting Championship titleholder with a lunging right hand and followed with rapid-fire ground-and-pound. Roberts turtled and tried to escape, only to wander deeper into peril. Aurelio rolled into an armbar, maximized torque and forced the American to capitulate.

Nearly 18 years later, Aurelio’s finish of Roberts still ranks as the fastest submission in the history of the UFC lightweight division. The best of the rest: Terry Etim vs. Edward Faaloloto UFC 138 Nov.

5, 2011 | Birmingham, England Etim swept aside the Hawaiian with a guillotine choke in the first round of their lightweight attraction at LG Arena. Faaloloto clocked out a cool 17 seconds into Round 1. Providing support for the Chris Leben - Mark Munoz headliner, Etim connected with a spinning back kick to the body and coaxed his adversary into an ill-advised takedown attempt.
