During the prelims of UFC 181, Josh Samman KO’d Eddie Gordon at 3:08 of the second round with one of the most devastating head kicks in UFC history. After missing nearly a year with a hamstring injury, Samman showed no effects from that injury. He attempted a bunch of kicks that were close to landing, but after referee Herb Dean separated to two fighters for lack of movement on the ground, Samman unleashed the fury.
