It's the biggest night the heavyweight division has ever seen, as four of the best in mixed martial arts enter the Octagon. In the UFC 146 main event, heavyweight champion Junior Dos Santos defends his belt against Frank Mir, who looks to become only the second man to win the title three times. But that's not all. Former champion Cain Velasquez hits the comeback trail in a pivotal matchup with Brazilian star Antonio "Bigfoot" Silva.
