If you weren't watching Amazon Forest Combat (AFC) 2 last night (Sat., March 31, 2012) from the Amadeu Teixeira Gymnasium in Manaus, Amazonas, Brazil, then you missed what could be the knockout of the year.
Even if it wasn't scored as one.
That's because Ultimate Fighting Championship (UFC) and longtime mixed martial arts (MMA) veteran Pete Spratt, at the ripe old age of 41-years-old, absolutely obliterated Daniel Acacio with a spinning backfist knockout right as the final horn sounded.
Naturally, he was awarded the decision win.
