The former two-division champion was the first fighter to to the scale and he showed up at championship weight, coming in at 155 pounds for Saturday’s headliner against Dustin Poirier. Poirier also successfully hit the mark at 156 pounds to make the rematch official.
In the first meeting between Poirier and McGregor at UFC 178 in September 2014, McGregor defeated Poirier by first-round TKO.
The weigh-ins were not without drama however, as two fighters did not make it to the scale and two others missed weight on their first attempts.
Officials announced early in the proceedings that Ottman Azaitar was out of his main card lightweight bout with Matt Frevola due to “a recent violation of the health and safety protocols involving” Azaitar, per the UFC. Frevola still showed up and made weight at 155.5 pounds.
Lightweight Nasrat Haqparast did not make an appearance during the two-hour weigh-in window and he will not be competing on Saturday. Officials later announced his withdrawal was due to an illness. Haqparast’s scheduled opponent Arman Tsarukyan also had difficulties, coming in three pounds over the lightweight limit at 159.
Tsarukyan was given an additional hour to cut weight, but could only make it down to 157 pounds on his second attempt. However, a matchup between Frevola and Tsarukyan has been arranged with Tsarukayn forfeiting 20 percent of his purse to Frevola, sources with knowledge of the change told MMA Fighting following an initial report by TSN.
Khalil Rountree also came in heavy, weighing in 0.5 pounds over the 205-pound limit (including a one-pound allowance for non-title fights). He was given an additional hour to make weight and successfully did so on his second attempt, coming in at 206 pounds.
