Adrian Curiel and Sivenathi Nontshinga have satisfied their final obligation to move forward with their rematch.

Both boxers were well within the rehydration allowance for the IBF-mandated second-day weigh-in. All participants in IBF-sanctioned fighters are required to weigh no heavier than ten pounds above the contracted weight limit on the morning of the fight. 

Curiel weighed 116.4 pounds, well within the 118-pound mark he was required to make on Friday morning. Nontshinga clocked in slightly heavier at 116.9 pounds ahead of Friday's IBF junior flyweight title fight rematch.

The weights represent a nine-pound gain for each from Thursday's official weigh in; Curiel was 107.4 pounds ahead of his first title defense, while Nontshinga was 107.9 pounds, just under the divisional limit in a bid to regain his old title.

Their bout headlines a DAZN show which will air live Friday evening from Oaxaca, Mexico beginning at 8:00 p.m. ET/7:00 p.m. local time.

Curiel was the author of one of the biggest upsets of 2023 when he scored a stunning first-round knockout of the previously unbeaten Nontshinga (12-1, 9KOs) last November 4 in Monte Carlo, Monaco. He entered the fight—his first outside of Mexico—as the slightly heavier challenger at 107.9 pounds. Nontshinga weighed 107.7 pounds ahead of his second attempted title defense.

Mexico City’s Curiel (24-4-1, 5KOs) returns to his home country for Friday’s scheduled twelve-round main event.

Nontshinga last traveled to Mexico in his title-winning effort over then-unbeaten Hector Flores. Their September 2022 scorcher from Hermosillo saw Nontshinga score an early knockdown and ultimately prevail via split decision.

His lone successful defense came in a twelve-round unanimous decision victory over unbeaten mandatory challenger Regie Suganob last July 2 in his hometown of East London, South Africa.
