Defending heavyweight champion Jon Jones arrived on the scale late in the window and tipped the scale at 237.5 pounds, while former two-time champion Stipe Miocic came in 11.1 pounds heavier, at 248.6 pounds.
The co-main event will see rival lightweights collide for the second time, with both Charles Oliveira and Michael Chandler looking to earn a shot at lightweight champion Islam Makhachev.
Their goals are the same, and their weights were also identical, as they both registered official weights of 155.6 pounds apiece for their eagerly-anticipated lightweight contender clash.
Middleweights Bo Nickal (185.4) and Paul Craig (186) also had no problem making weight, as did most of the rest of the card.
Twenty-five out of 26 fighters made their contracted weights, with the one exception being lightweight James Llontop, who was unable to make weight for his 165-pound catchweight bout with Mauricio Ruffy.
Llontop came in 1.2 pounds over the limit and was fined 20 percent of his purse as a result. The fight will go ahead as planned, and will kick off the pay-per-view main card on Saturday night.
After the official weigh-ins were complete, the fighters rehydrated and refuelled ahead of the evening’s ceremonial weigh-ins, where they faced off for the final time in front of a rowdy New York crowd.
