California middleweight Hugo "The Boss" Centeno Jr. (27-3) will battle Mexico's Juan Macías Montiel (21-4-1) in a ten-round clash that headlines on FS1 and Fox Deportes Saturday, December 21st at Toyota Arena in Ontario, California. The FS1 telecast will also feature 2016 U.S. Olympian Karlos Balderas (15-1 including the World Series of Boxing) taking on Mexico's René Téllez Giron (13-1) in an eight-round lightweight duel and Texas' Raymond Guajardo (4-0) battling New Orleans-native Donnis Reed (3-4) at junir middleweight. The FS1 telecast precedes the Fox Fight Night broadcast from the same venue headlined by rematch between WBC junior middleweight champion Tony Harrison and his predecessor, Jermell Charlo.

 

Fighting out of his hometown of Oxnard, California, Centeno (27-3, 14 KOs) will look to bounce back after he lost a close decision to Willie Monroe Jr. in June. The 28-year-old had won three out of four fights heading into the Monroe fight, including a highlight-reel knockout of then-unbeaten Immanuwel Aleem on FS1 in August 2017. He will step into the ring for the third time in 2019 on December 21st, having also defeated Oscar Cortes in February.

 

The 25-year-old Montiel (21-4-1, 21 KOs) has fought professionally since 2009 and most recently stopped fringe contender Marcos Reyes in February by fourth-round TKO. Representing Los Mochis, Mexico, Montiel will make his U.S. debut on December 21st, in a career that has seen him knockout then-unbeaten Ivan Montero and drop a 2017 contest to eventual title holder Jaime Munguia.

 

A 2016 U.S. Olympian, Balderas returns for an eight-round lightweight affair to close out 2019. The 23 year-old from Santa Maria, California has won his last five fights by stoppage, including three in 2019. His most recent outing saw him stop Robert Frankel in July. He will be opposed by the 20 year-old Giron (13-1, 7 KOs), who fights out of Queretaro, Mexico and is looking to rebound from a decision loss to unbeaten Michel Rivera in June.

 

Guajardo (4-0, 3 KOs) turned pro one week after his 19th birthday this March and kicked off his career with a second-round knockout of Leonardo Mendez in his hometown of San Antonio, Texas. Guajardo will enter the ring on December 21st in a four or six-round contest seeking his fifth win of 2019. He most recently defeated Brian Urday by first-round knockout in October and will be opposed by the 34 year-old Reed (3-4, 2 KOs) as he steps into the ring for his third fight of 2019.
