Sensational 2016 U.S. Olympian Karlos Balderas takes on Mexico's Rene Tellez Giron in an eight-round lightweight match as the opener of FOX PBC Fight Night live in primetime and on FOX Deportes this Saturday, December 21 at Toyota Arena in Ontario, California at 8 p.m. ET/5 p.m. ET.
 
Former champion Guillermo Rigondeaux was scheduled to take on Liborio Solis in the co-feature of the FOX PBC Fight Night card, but that match has been postponed until a later date.
 
Balderas vs. Giron will serve as the opening attraction to the show that is headlined by the highly anticipated rematch between WBC Super Welterweight Champion Tony Harrison and former champion Jermell Charlo that also features Efe Ajagba taking on Iago Kiladze in a 10-round heavyweight showdown in the co-feature.
