The fight will headline a Fox pay-per-view card. The fighters and their teams gathered to meet the media at Staples Center hours before the Errol Spence Jr.-Shawn Porter welterweight title unification bout at the arena.
Premier Boxing Champions also announced the co-feature, in which featherweight world titlist Leo Santa Cruz will go for a belt in a fourth weight division when he moves up to junior lightweight to face Miguel Flores for a vacant 130-pound title.
Santa Cruz (36-1-1, 19 KOs), 31, of Rosemead, California, who has won world titles at bantamweight, junior featherweight and featherweight, will leave behind the featherweight division having had two title reigns and having made three defenses in his current reign, but not having had the major fight he could have had: a title unification bout against fellow PBC fighter Gary Russell Jr.
"When I first started boxing my dream was to be a world champion, and I've been fortunate to win three different world championships in three different divisions," Santa Cruz said. "I couldn't imagine winning championships in four divisions. It's something I never really dreamed of, and I'm very happy about this opportunity.
"I know Flores is another tough Mexican boxer like me. He always comes forward, so it's going to be a fun fight for the fans. I'm really looking forward to fighting again in Las Vegas at MGM Grand. It's going to be a really exciting atmosphere because you have Deontay Wilder and Luis Ortiz in a heavyweight championship fight, and Deontay always knocks his opponents out, but we're hoping that our fight will steal the night."
Santa Cruz was supposed to defend his featherweight belt against Flores (24-2, 12 KOs), 27, of Houston, on Feb. 16 in Los Angeles, but Flores suffered an ankle injury and withdrew, and Santa Cruz instead outpointed Rafael Rivera in a one-sided fight.
Flores has won two fights in a row, both in the junior lightweight division.
"I'm extremely excited to be getting this opportunity once again to fight Leo Santa Cruz and win a world title," Flores said. "Being the co-main event on this Fox Sports PBC pay-per-view card with Wilder versus Ortiz headlining is incredible. This is a dream come true for me, and I'm going to take advantage of the situation.
"This moment in my life is something I've envisioned since I was a kid. On Nov. 23, you will see the best version of myself as I plan to be in the best shape of my life, with the goal of becoming a world champion, and what better way to do it than in Las Vegas at MGM Grand. Leo and I are going to put on a great show, that you can guarantee."
