Ramirez (38-0, 25 KOs) will defend his WBO super middleweight world against Hart (25-1, 21 KOs) Friday at the American Bank Center in Corpus Christi, Texas, site of his February knockout of Habib Ahmed. Ramirez bested Hart via unanimous decision last September in one of the finest world championship fights of 2017.

In the co-feature, unbeaten 140-pound contender Arnold Barboza Jr. (19-0, 7 KOs) will face Manuel Lopez (14-2-1, 7 KOs) in a 10-rounder.

Ramirez-Hart 2 and Barboza-Lopez will stream live at 10 p.m. ET on ESPN+. The entire undercard, including appearances by female fighting sensation Mikaela Mayer, 130-pound contender Jamel Herring, Gabriel Flores Jr., and big-punching bantamweight Joshua Greer Jr. will stream live on ESPN+ beginning at 6:30 p.m. ET.
