Anthony Pettis flattened Stephen Thompson in the UFC Fight Night 148 headliner on Saturday in Nashville, Tennessee, as an Ultimate Fighting Championship event saw a longtime lightweight knock out a former welterweight title challenger for the second time in as many weeks.
Pettis entered the bout desperate for a victory, having won just three of his previous nine fights. After being bloodied up by the karateka for the better part of 10 minutes, the former lightweight champion threw a Superman punch that left Thompson on the canvas in an unconscious heap.
