Chris Weidman sent a shock wave through mixed martial arts, stopping Anderson Silva in the second round of the main event at UFC 162 to become the new middleweight champion on Saturday night. Silva talked, taunted and dared Weidman to engage him. When the champion lowered his hands early in the second round, Weidman caught him with a short left that sent the MMA star to the mat. Weidman pounced and landed a few more shots that forced referee Herb Dean to stop the fight at 1:18
