UFC 176: Aldo vs. Mendes II was a cancelled mixed martial arts event that was scheduled to be held by the Ultimate Fighting Championship on August 2, 2014, at Staples Center in Los Angeles, California.

The first man to hold the UFC flyweight title, Demetrious "Mighty Mouse" Johnson, has gone on to dominate his division, defeating opponent after opponent. But Johnson has not cleaned out the 125-pound weight class yet, and dynamic striker Chris "Kamikaze" Cariaso is prepared to prove that fact to the champion at UFC 178.
