Nurmagomedov was the first fighter to step on the official scale, hitting 155 pounds on the nose. Just over an hour later, McGregor did the same, weighing in at 154.5.
Nurmagomedov is unbeaten in his career, coming off a decision win over Al Iaquinta to claim the vacant UFC title. McGregor was the first-ever dual UFC champion when he finished Eddie Alvarez in 2016 to claim the belt while holding the featherweight title at the same time.
The two nearly came to blows earlier this year when McGregor and members of his team stormed the Barclays Center in search of Nurmagomedov after "The Eagle" had confronted McGregor's teammate, Artem Lobov, during fight-week.
In the co-main event, former interim champion Tony Ferguson returns to action for the first time since last year when he collides with ex-UFC and WEC lightweight titleholder Anthony Pettis. The main card also features Derrick Lewis vs. Alexander Volkov and Michelle Waterson vs. Felice Herrig.
