Originally scheduled as a bantamweight bout, the fight between former two-time UFC Featherweight Champion and UFC Hall of Famer (also former WEC Featherweight Champion) José Aldo and Aiemann Zahabi was moved to featherweight on the day of the weigh-ins, with Aldo weighing in at 143 pounds and Zahabi at 142 pounds. After the official weigh-ins, Zahabi disclosed that his team was told Aldo's weight cut was going to be a problem and said he was just under 137 pounds at the time. Had he made weight, Aldo's weight discrepancy would have meant an automatic cancellation of the bout. Instead, Zahabi stopped his weight cut and had to rehydrate for a fight at featherweight so he could be close enough to Aldo's missed weight to avoid the fight being scrapped entirely.[15]
In addition, at the weigh-ins, Bruno Silva weighed in at 187 pounds, a pound over the weight non-title fight limit. The bout proceeded at catchweight and Silva was fined 20 percent of his purse which went to his opponent Marc-André Barriault.[16]
