LAS VEGAS – Sebastian Fundora joked earlier this week that he would be in the 154lbs division for an extended period because he’s incapable of putting on weight.

At Friday’s weigh-in for the first defense of his WBO and WBC junior middleweight belts at Mandalay Bay, his words were prophetic as he came in more than a full pound under the weight limit, at 152.8 pounds.

Fundora’s opponent, No. 5-rated WBO contender Chordale Booker of Connecticut, also came in light at 152.6 pounds.

Standing 6ft 5 ½ins with an 80-inch reach, the lanky Fundora said after weighing in that he trained as he always does in the mountains above the Coachella Valley.

“The only difference is I’m a world champion,” he said. “We’ve just got to prove again why we’re here.”

Heavily favored at -1200, Southern California’s Fundora, 21-1-1 (13 KOs), learned earlier on Friday that he may be required in victory to meet the likely new WBO mandatory contender Xander Zayas of Puerto Rico.

Terence Crawford relinquished his interim WBO title and informed the WBO he’s leaving the division to pursue his mid-September super middleweight title fight against unified champion Canelo Alvarez.

Booker, 23-1 (11 KOs), said he’s “extremely ready” to pursue the upset.

“The only people who think I’ll win is my family,” the 5-feet-9 Booker said. “Everyone else thinks I’m a bum, I’m going to get killed. I know he’s 6-6 … I’ve accepted the challenge.” 

In other Prime Video bouts, junior-middleweight top-10 contender Jesus Ramos Jnr weighed 155.8lbs for the contracted 156-pound bout against Guido Emmanuel Schramm, who came in at 154.6lbs. 

Middleweight Elijah Garcia, 21, hit the scales at 159.6lbs. His veteran opponent, two-time title challenger Terrell Gausha, 37, weighed 160.2, slightly over the limit. An agreement was struck afterwards to ensure the fight will still happen.

In a welterweight bout scheduled for eight rounds, Freddie Rojas Jnr (150lbs) and Maurice Lee (151.4lbs) made weight for their contracted-weight bout, and lightweights Robert Guerrero Jnr (133lbs), the son of former two-division champion Robert “Ghost” Guerrero, and Sean Armas (132.6lbs) also made weight.
