Miguel Vazquez will enter this ring this weekend at his lightest weight in more than a decade.

The former IBF lightweight titlist weighed 134 pounds for his scheduled 10-round contest versus Nicaragua’s Oliver Flores, which takes place Saturday evening live on ESPN+ and IFL TV from Verite Social Club in Monterrey, Mexico.

Flores (30-3-2, 19KOs) was slightly heavier, though at 134 ½ pounds still well within the lightweight limit. It is the lightest weight for the 30-year-old southpaw since 2017, when he weighed 134 pounds in a ten-round decision defeat to then-unbeaten lightweight prospect Felix Verdejo.

Vazquez has campaigned at junior welterweight since 2016, moving up after a loss to Argenis Mendez in October 2015. The defeat came two fights after dropping a twelve-round, split decision to Mickey Bey in September 2014, bringing an end to his four-year IBF lightweight title reign.

Among his eight successful defenses was a twelve-round win over Ricardo Dominguez in November 2010, where Vazquez weighed a career-low 133 ½ pounds. Vazquez became the first to beat Breidis Prescott prior to winning the belt, which he defended against unbeaten contenders Leonardo ‘Lenny Z’ Zappavigna, Mercito Gesta and Denis Shafikov over the course of his lengthy title reign.

Mixed results have come of Vazquez’s tour at junior welterweight, including the first stoppage loss of his career in falling to Josh Taylor inside of nine rounds in November 2017. Taylor has since become the undisputed junior welterweight champion.

Vazquez’s last true fight at junior welterweight came last October, landing on the wrong end of a highly questionable twelve-round, split decision in favor of Lewis Ritson. He has since returned to lightweight, earning a seventh-round stoppage of Isai Hernandez this past April at this very venue.

Flores has won three straight, though fighting for the first time since September 2019. The well-traveled Nicaraguan has only lost to the sport’s top talents, with defeats coming versus Verdejo, Miguel Berchelt—who went on to enjoy a lengthy junior lightweight title reign—and then-unbeaten WBC junior lightweight titlist Takashi Uchiyama in December 2015.

In the co-main event, undefeated heavyweight Brandon Moore (9-0, 5 KOs) is back, facing Jesus Angel ‘Dandy’ Nerio (15-9-1, 6 KOs) for the WBC USNBC heavyweight title. Moore weighed 244.5, while Nerio—who moved up to heavyweight last November—weighed a career-high 213.9 pounds.
