for the fourth time in four years, the bout fell apart, as ferguson pulled out of the fight on april 1 due to a knee injury. he was replaced by current ufc featherweight champion max holloway. if successful, holloway would become only the second fighter to be champion in two divisions simultaneously (after mcgregor who won the lightweight title at ufc 205 when he was the reigning featherweight champion) as well as the fifth overall to win titles in different divisions. on weigh in day, the main event suffered another set back as holloway was deemed medically unfit to compete and then removed from the event. the ufc targeted former lightweight champion anthony pettis as his replacement, after pettis' bout against michael chiesa was scrapped due to an incident caused by mcgregor ("see section below"). pettis weighed in at 155.2 pounds in his first attempt, and despite being given extra time to make the championship weight limit of 155 pounds, he did not weigh in again.
