Adrien Broner believes he has a lot of championship-caliber boxing left in him.

The polarizing Broner has been a pro for nearly 13 years and has almost 40 fights on his record. The Cincinnati native is still just 31, however, and feels as though he remains in his physical prime.

Broner scoffed when asked during a recent episode of Brian Custer’s “The Last Stand Podcast” about skeptics considering him past his prime.

“I’m only 31,” an incredulous Broner told Showtime’s Custer. “I’m only 31. How can I be past my prime? It’s just I’ve done so much in the sport at a early age, that it may seem like I’ve been in the game forever. But I’m very young. I haven’t took much punishment. I got too much more fight in me.”

The four-division champion, who made his pro debut in May 2008, should be refreshed physically entering his upcoming bout because Broner hasn’t boxed in more than two years. His fight February 20 against Jovanie Santiago will be Broner’s first action since he lost a lopsided, 12-round unanimous decision to Filipino legend Manny Pacquiao in January 2019 at MGM Grand Garden Arena in Las Vegas.

Broner (33-4-1, 24 KOs, 1 NC) is heavily favored to topple Puerto Rico’s Santiago, but the 31-year-old Santiago is undefeated (14-0-1, 10 KOs). As BoxingScene.com first reported, Santiago replaced Pedro Campa as Broner’s opponent because Mexico’s Campa (31-1-1, 21 KOs) tested positive for COVID-19 shortly after committing to box Broner.

When he squares off against Santiago, Broner will attempt to record his first convincing victory in the near five years that have passed since he stopped England’s Ashley Theophane in the ninth round of their April 2016 bout in Washington, D.C.

Broner is 1-2-1 in his past four fights. His lone win during that stretch was a debatable, 10-round, split-decision victory over Adrian Granados (20-8-2, 14 KOs, 1 NC) in February 2017 in Cincinnati.

The Broner-Santiago fight will headline a “Showtime Championship Boxing” tripleheader February 20 from Mohegan Sun Arena in Uncasville, Connecticut.

Heavyweights Otto Wallin (21-1, 14 KOs, 1 NC), of Sundsvall, Sweden, and Dominic Breazeale (20-2, 18 KOs), of Eastvale, California, are set to square off in the co-feature. In Showtime’s opening bout that night, former IBF lightweight champion Robert Easter Jr. (22-1-1, 14 KOs), of Toledo, Ohio, is set to encounter Ryan Martin (24-1, 14 KOs), of Chattanooga, Tennessee.
