UFC 178 Extended Preview: Johnson vs. Cariaso, Cowboy vs. Alvarez, and McGregor vs. Poirier

UFC flyweight champion Demetrious “Mighty Mouse” Johnson has dominated 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. Plus, top contender Donald “Cowboy” Cerrone will battle international lightweight star Eddie Alvarez, who is making his UFC debut. Also, Dustin Poirier will face Irish superstar Conor McGregor.
