Undefeated super welterweight prospect Ardreal Holmes will now face once-beaten Vernon Brown in the 10-round main event of ShoBox: The New Generation on Friday, March 11 live on SHOWTIME at 9:35 p.m. ET/PT from Deadwood Mountain Grand Hotel in Deadwood, S.D.

Mekhrubon Sanginov, who was originally slated to take on Holmes (11-0, 5 KOs) in the main event, was forced to withdraw from the bout after suffering an injury in training camp.

Brown (13-1-1, 9 KOs), who was previously set to fight the undefeated Hurshidbek Normatov in the co-main event, steps in to face Holmes. Normatov also suffered an injury in training camp and is unable to fight on March 11.

The previously-announced eight-round lightweight matchup between undefeated prospect Luis Acosta (12-0, 11 KOs) and the power-punching Edwin De Los Santos (13-1, 12 KOs) serves as the co-main event and 2021 National Golden Gloves Champion Giovanni Márquez, the son of former world champion and ShoBox commentator Raul Márquez, makes his professional debut against Dominican Nelson Morales (2-0) in a four-round super lightweight bout that opens the three-fight telecast. Raul Márquez will occupy dual roles during the broadcast, first as his son’s trainer and cornerman and then later as an expert analyst alongside his colleagues ringside.

The event is promoted by Holden Productions.
