Saturday, March 11, 2017, during a fight in the UFC Fight Night 106 organized in Fortaleza, in the Brazil, the Brazilian fighter Edson Barboza has come to know his opponent, the Iranian Beneil Dariush, before the fatal blow. Noting that the latter performed regularly linking punch to the face/legs, Edson Barboza waited the right time, in the second round, to break this sequence giving a violent knee to the face of Beneil Dariush when he bent down again to grab the legs. The Iranian was immediately knocked out.
