Moicano, of Brazil, hit his mark at 146 pounds. "The Korean Zombie" also weighed in at 146. Neither featherweight competitor can weigh more than 146 pounds one day prior to their fight.
Moicano (13-2-1) has won three of his past five matchups -- including against tough opponents Cub Swanson, Calvin Kattar and Jeremy Stephens -- but will look to rebound from a second-round TKO loss to former champion and fellow Brazilian Jose Aldo at UFC Fortaleza in February. Moicano, 30, is looking to get back in the featherweight title picture Saturday.
Rodriguez, likely down on the judges' scorecards through most of that bout, landed a hard elbow with one second remaining to claim the victory.
Jung, 32, has fought just twice since 2013 due to injuries and his obligatory military service in South Korea.
UFC Fight Night: Moicano vs. Korean Zombie will begin at 4 p.m. ET Saturday on ESPN 2 and move to ESPN+ at 7 p.m.
The card lost its scheduled co-main event Friday morning. John Lineker suffered a cut Thursday night and withdrew from his bantamweight bout with Rob Font. The UFC has not announced whether Font will remain on the card.
The rest of the fighters on the card made weight.
