Poirier (9-1), part of the WEC-UFC merger, is coming off back-to-back wins over Zach Micklewright at WEC 52 and Josh Grispi at UFC 125. Poirier stepped in last-minute to face the higher ranked Grispi at UFC 125 when featherweight champion Jose Aldo dropped off the card. To the surprise of many, he dominated Grispi, propelling himself into the Top 10 ranks.
Following a roller coaster ride at bantamweight, including losing his final two WEC bouts at 135 pounds, Yahya (16-6) returned to featherweight for his Octagon debut. He dominated Mike Brown en route to a unanimous decision at UFC Fight For The Troops 2.
A heavyweight bout pitting “Ultimate Fighter Season 13″ coaches Brock Lesnar and Junior Dos Santos against one another is expected to headline UFC 131 at Rogers Arena.
