A disoriented and severely bloodied Brock finished the fight on his back being fed several blows to the face. Despite a frightening opening charge by Lesnar which including flying knees, punches in bunches and 2 takedowns, referee Herb Dean had no choice but to stop the fight at 4:01 of round 1. Brock Lesnar did not survive the first round of Saturday night's UFC Heavyweight championship bout against undefeated challenger Cain Velasquez.
