Poirier (29-8) announced the fight was off via social media, and told ESPN he and the UFC were unable to come to financial terms for the bout. Poirier later clarified it was a "misunderstanding" on his part, and the fight is back on.
Poirier, 35, hasn't fought since he suffered a knockout loss to Justin Gaethje in a BMF title fight in July. He is coming off the most high-profile stretch of his career, a three-year run that has included two fights against Conor McGregor, a title fight against Charles Oliveira, a fan favorite bout with Michael Chandler and the BMF fight.
Saint Denis, 28, is on a five-fight win streak.
