Ryan Jimmo defeated Anthony Perosh by knockout (punch) at :07 of round one
I spent a lot of time trashing Ryan Jimmo's boring style in the leadup to this bout. Well, Ryan Jimmo sure shut me up, and all of his other detractors. The bell rang for his UFC 149 light heavyweight bout with Anthony Perosh, he stepped forward and touched gloves, then knocked out Perosh with one monster right hand right behind the ear.
Let me repeat something I never, ever thought I'd have to type - Ryan Jimmo knocked someone out. In seven seconds.
The shot dropped Perosh to the mat, unconscious. He followed it up with one more shot on the ground, but it was already over. Jimmo tied the official UFC record for fastest knockout, though everyone knows that Duane Ludwig really holds that record.
Either way, it was a huge splash for Jimmo in his debut and he'll look forward to bigger and better things in the octagon.
