UFC featherweight Dustin Poirier has three losses on his record but only one that truly irks him. This past February, Poirier stepped up to the plate to face Cub Swanson as a replacement with less than a month to prepare. The 24-year old was beaten badly and is still bothered by the loss. Earning an eventual shot at redemption is one of the many factors motivating “The Diamond” entering his December 28 tilt against Diego Brandao at UFC 168. Poirier spoke to UFC.com about the challenge at hand, the fight he wants, an added bonus to his training camp, and much more.
