Officials confirmed the 145-pound contest on Friday, following an initial report by MMAJunkie. UFC Fight Night will take place at CFO Arena and air on ESPN+.
Prior to beating Stephens, Aldo was 0-2 in his last two fights -- both of which came against current champ Max Holloway. Aldo, 32, is 2-3 in his last five matches, but remains on the cusp of title contention at 145 pounds.
Fighting out of American Top Team in Coconut Creek, Florida, Moicano was pegged as a backup for a featherweight title fight between Holloway and Brian Ortega at UFC 231 earlier this month, but failed to make championship weight. It was a potentially embarrassing moment for the 29-year-old, but did not cost him much in terms of rank.
ESPN.com ranks Aldo and Moicano the Nos. 3 and 5 featherweights in the world, respectively.
