No one saw this coming. Sanchez ko’s Riggs. Ok, I thought Sanchez would win, but not by KO, especially against Joe Riggs. Diego drops Riggs with a head blow, as Riggs tries to get of the ground Sanchez lands a huge knee to Riggs’s jaw. Riggs is out and Big John stops the fight. Our reader poll had it Diego by submission 44% and Diego winning by KO 18%.
