The fight will take place at UFC 281 in November and is scheduled for three rounds.In the build-up to their clash, 'The Diamond' and 'Iron' sat down to do an interview with Daniel Cormier to discuss the issues between them. Cormier asked the two lightweights why they can't seem to get on the same page, and Poirier said:"This is just it, the way he answered that question is not who he was a few interviews ago with Ariel Helwani. Or it's not who he was when the mic's in front of him in the octagon. He was a different guy whenever we sat next to each other in Abu Dhabi and spoke."Chandler interjected:"The guy that talked to you in Abu Dhabi in the stands, you and I in the stands, before weigh-ins, we had all of that. And then that Dustin Poirier went on record on the microphone after the fight and said, 'If the UFC wants me to fight Michael Chandler, I'd just as soon go sell hot sauce.'''Watch the video below from 1:00:As we edge closer to UFC 281, it will be fascinating to see whether Poirier and Chandler increase the intensity of their verbal exchanges or let bygones be bygones.
