Ring City USA, the new sports media startup that debuted its Thursday night boxing series in November 2020, has unveiled undercard fights for their March 4 and March 18 events, three weeks ahead of their residency in Puerto Rico.

All events will be televised in the United States and Puerto Rico on NBC Sports Network and the NBC Sports app on Thursday nights at 9 p.m. ET/6 p.m. PT with undercard action streaming live on Twitch.

On March 4, Ring City will take over the Felix Pagan Pintor Gym in Guaynabo with the previously-announced main event between undefeated blue-chip rising star Serhii Bohachuk (18-0, 18 KOs) and former middleweight title challenger Brandon Adams (22-3, 13 KOs) for the vacant WBO NABO Jr. Middleweight title in a 10-round affair. In the co-main event on NBCSN, undefeated prospect Danielito Zorilla (14-0, 11 KOs) of Rio Piedras, Puerto Rico, will meet Kazakhstan’s Ruslan Madiyev (13-1 5 KOs) for the WBO NABO Jr. Welterweight title in a 10-rounder.
