Jesus Antonio Perez Campos replaces Vergil Ortiz Jr.; will face Michael McKinson

Michael McKinson is prepared to make the most of his U.S. debut.

FightNights.com has learned that Jesus Antonio Perez Campos will step in as a late replacement opponent to face England's McKinson after being approved by the California State Athletic Commission (CSAC) on Wednesday. Tijuana's Campos (24-3, 18 KOs), who last fought in December 2019, fills the void left behind by unbeaten welterweight contender Vergil Ortiz Jr. (18-0, 18 KOs), who abruptly withdrew from Saturday's main event after being hospitalized earlier this week for rhabdomyolysis.

While the CSAC approved the fight, the bout has yet to be signed off by McKinson's promoter, Matchroom Boxing, although it is expected they will. But while McKinson's spot has been saved, it will no longer occupy the main event slot.

The card's original chief support bout between welterweight prospects Blair Cobbs (15-0-1, 10 KOs) and Alexis Rocha (18-1, 12 KOs) has been elevated to the main event. McKinson-Perez will be demoted to the co-feature position.

Perez is coming off an eight-round unanimous decision victory over Mexican journeyman Ramon Barajas (13-26, 4 KOs). The triumph came two months after nearly getting shutout by Puerto Rico's Danielito Zorrilla (16-0, 12 KOs).
