Unbeaten super middleweight contender Diego Pacheco will face fellow undefeated rival Kevin Lele Sadjo in a high-stakes matchup headlining a December 13 DAZN show at the Adventist Health Arena in Stockton, California. Matchroom Boxing confirmed the main event on Saturday, marking another key test for one of boxing’s fastest-rising 168-pound talents.
The card will also feature Ernesto “Tito” Mercado, who is still awaiting confirmation of his opponent, and local favorite Gabriel Flores Jr., whose return to his hometown is expected to help fill the 12,000-seat venue. It will be Flores’ fifth appearance in Stockton and adds a strong regional draw to the show.
Pacheco (24-0, 18 KOs), 24, will make his third appearance of 2025 following 12-round decision wins over Steven Nelson in January and Trevor McCumby in July. Those bouts marked the first time he was extended beyond ten rounds. The Californian recently split with longtime trainer Jose Benavidez Sr. in an amicable parting, and his new corner team has not yet been announced.

Sadjo (26-0, 23 KOs), a 35-year-old Cameroonian Frenchman, will make his U.S. debut after compiling an impressive knockout record across Europe and Africa. Though highly ranked, Sadjo’s career has been defined as much by missed opportunities as victories — most notably the canceled IBF eliminator against Christian Mbilli earlier this year. He has since recorded back-to-back stoppage wins, most recently halting Martin Ezequiel Bulacio in August.
Both fighters enter ranked inside the WBO’s top 10, with Pacheco sitting at No. 3 and Sadjo at No. 8, potentially placing the matchup in line for title contention or eliminator status.

▪️Diego Pacheco vs. Kevin Lele Sadjo, 12 rounds, super middleweight
