The Ring has confirmed that the IBF has called for a mandatory junior flyweight title fight between South Africa’s Nontshinga and the Philippines’ Christian Araneta. Both sides were notified by the sanctioning body on Tuesday to begin the negotiation period.

Nontshinga (13-1, 10 knockouts),The Ring’s No. 2-rated junior flyweight, is promoted by Matchroom Boxing. Araneta (24-2, 19 KOs) is represented by Pio Castillo of Omega Boxing Promotions.

The mandated title fight will serve as a rematch roughly three years after their first meeting. Nonthshinga survived a final round scoreto win their April 2021 IBF title eliminator via unanimous decision. He would go on to win the belt for the first of two times in his next fight.

Nontshinga regained the belt witha dramatic, tenth-round knockout of Adrian Curiel to conclude their February 15 rematch inOaxaca, Mexico. Their instant classic saw the 25-year-old from Reeston, S. Africa rally to drop and eventually stopThe Ring’s No. 3-ratedCuriel (24-5-1, 5 KOs) to avenge his lone career defeat.

Nontshinga was halted in the opening round in their first meeting last November 4 in Monte Carlo, Monaco. The defeat ended his first IBF title reign dating back to his thrilling Sept. 2022 split decision victory over then-unbeaten Hector Flores Calixto in Hermosillo, Mexico.

Araneta entered the queue when he knocked out Arvin Magramo in their all-Filipino title eliminator. The 28-year-old southpaw scored two knockdowns ina first-round knockout victory on January 24 in his Cebu hometown. The win was his fifth in a row since his defeat to Nontshinga. All but one during that stretch have inside the distance.
