VIDEO: Johnson retains flyweight title with submission win over Horiguchi

The king stayed the king in Montreal on Saturday night, as Demetrious Johnson retained the UFC flyweight title with latest submission in UFC history, finishing Kyoji Horiguchi via armbar with only one second left in the fifth and final round.

After a relatively competitive opening round, Johnson's impossibly furious pace, world-class conditioning and pressure wrestling took over, as he exhausted the challenger over almost 25 minutes.

The waning moments of the final stanza, Johnson - who had Horiguchi trapped in a crucifix - made a transition from raining down punches into a slick armbar, eliciting the tapout at 4:59.

A straight up spectacular finish by "Mighty Mouse."
