LAS VEGAS (AP) — Junior Dos Santos flattened Frank Mir with a huge right hand and finished him on the ground at 3:04 of the second round Saturday night, emphatically defending his heavyweight title at UFC 146 on Saturday night.
Dos Santos (15-1) picked apart the two-time ex-champion with superior boxing throughout the fight, eventually stunning Mir before finishing him with one last blow to the head. Dos Santos then wrapped himself in the Brazilian flag while celebrating his first fight since winning the title last fall.
Former heavyweight champion Cain Velasquez stopped Antonio "Bigfoot" Silva late in the first round after administering a bloody beating that both thrilled and horrified fans at the MGM Grand Garden.
Roy Nelson, Stipe Miocic and Stefan Struve also won on a pay-per-view card topped with five heavyweight fights, a first in UFC history.
