Jose Aldo vs. Chad Mendes

In their first meeting in January 2012, Aldo stopped then-unbeaten Mendes with one second remaining in the first round. Since then, Mendes has won five straight, most recently decisioning Nik Lentz in December 2013. Aldo, the only 145-pound champion in UFC history, has added three more successful title defenses since the Mendes bout, defeating Frankie Edgar, Chan Sung Jung and Ricardo Lamas. He looks to stamp a finish on this rivalry once and for all.
