Unbeaten super welterweight contender Bakhram Murtazaliev and unbeaten prospects Pablo Rubio Jr. and Amed Medina will compete in separate attractions that highlight the non-televised undercard lineup this Saturday, July 17 from AT&T Center in San Antonio in a Premier Boxing Champions event.

Murtazaliev will compete in an eight-round showdown against Massachusetts’ Khiary Gray, while the Los Angeles-native Rubio Jr. (12-0, 4 KOs) faces Bryan, Texas native Eric Manríquez (7-11-1, 3 KOs) in an eight-round super welterweight duel, plus the 18-year-old featherweight Medina (2-0, 2 KOs) battles South Carolina’s Reginald Hinson (1-0) in a four-round fight.

Originally from Russia and now fighting out of Oxnard, California, Murtazaliev (18-0, 14 KOs) has risen up the rankings since turning pro in 2014. The 28-year-old first debuted in the U.S. in 2016, scoring victories over then unbeaten fighters Botirsher Obidov and Alex Duarte within his first year stateside. After earning three wins in 2019, Murtazaliev stopped veteran Manny Woods in his last outing in September 2020. He will be opposed by Worcester, Massachusetts’ Gray (16-5, 12 KOs), who was unbeaten in his first 13 fights after turning pro in 2014. Most recently, Gray dropped a March 2019 contest against veteran contender Gary O’Sullivan.
