On this day: Mitrione and Fedor's double knockdown classic at Bellator 180

Nine years ago at Bellator 180, Matt Mitrione and Fedor Emelianenko produced one of combat sports' most memorable moments when both fighters landed simultaneous right hands and were knocked down together. Mitrione sustained the shallower damage, recovered first, and went on to finish Emelianenko with ground-and-pound for the TKO victory.
