The first man to hold the UFC flyweight title, Demetrious "Mighty Mouse" Johnson, has gone on to dominate his division, defeating opponent after opponent.

The UFC makes its historic first visit to Mexico. In the main event of UFC 180, Brazilian powerhouse Fabricio Werdum will attempt to win the interim heavyweight title when he takes on revered knockout artist Mark "The Super Samoan" Hunt.
