“I feel like I’m only starting, man,” the 32-year-old McGregor said this week. UFC 257 is co-headlined by title-contending lightweights Dan Hooker and Michael Chandler, who is making his UFC debut after a decade in the rival Bellator promotion. McGregor spoke of wanting to fight four times in 2020, culminating in another shot at lightweight champion Khabib Nurmagomedov. McGregor and Poirier were even smaller — two up-and-coming featherweights — when they met in September 2014 in the third-billed bout at UFC 178. McGregor stopped Poirier just 1:46 into the opening round, landing a big left hook to the ear that ended the action swiftly.
