Zepeda is a little more than a year removed from challenging junior welterweight world champion Jose Ramirez in Ramirez’s backyard of Fresno, California. He fell short via majority decision, but many experts believed he’d done enough to win the title. Zepeda shined on the Tyson Fury-Otto Wallin undercard last September at T-Mobile Arena, outboxing former two- weight world champion Jose Pedraza over 10 rounds. Castaneda, from San Antonio, stepped in after Zepeda’s original opponent, Ivan Baranchyk, suffered an injury in training. Castaneda hopes to rebound from his first career loss, a majority decision to fellow unbeaten Yomar Alamo in February.
