The two men had faced off twice before and talked a lot of trash in the lead-up to the match at T-Mobile Arena in Las Vegas, but Poirier came out on top in the short contest.
McGregor (22-5) and Poirier (27-6) are longtime rivals. In 2014, McGregor defeated Poirier at UFC 178 with a first-round KO. But in January, Poirier got his revenge at UFC 257 with a second-round finish.
