Jeison Rosario intends to show Saturday night that he is much more the fighter that upset Julian Williams than the boxer Jermell Charlo knocked out in his last fight.

Rosario realizes there is a faction of fans and media that believe his surprising fifth-round stoppage of Williams was an aberration. That’s among the reasons that the 26-year-old Rosario didn’t hesitate to take a difficult fight against Erickson Lubin on the Gervonta Davis-Mario Barrios pay-per-view undercard at State Farm Arena in Atlanta.

The Dominican Republic’s Rosario (20-2-1, 14 KOs) will box Lubin in his first fight since Charlo dropped him three times and knocked him out with a body shot in the eighth round September 26 at Mohegan Sun Arena in Uncasville, Connecticut.

“What happened with the Charlo fight, that was the fluke,” Rosario said during a recent virtual press conference. “Me winning the titles wasn’t the fluke. And I’m gonna show that I will bounce back from that and, figuratively speaking, get off the canvas and win my next fight. So, I have no problem taking the fight. I don’t feel it was a mistake. This is what we do. We fight. And so, I’m very excited for June 26th. I expect Lubin to bring his best, as do I.”

Facing Rosario, a former IBF/IBO/WBA 154-pound champion, is a risky proposition for Lubin as well. The strong southpaw from Orlando, Florida, is already the WBC’s number one contender for Charlo (34-1, 18 KOs), who will battle Brian Castano (17-0-1, 12 KOs) in a full title unification fight July 17 at AT&T Center in San Antonio.

Lubin (23-1, 16 KOs) could’ve taken a less dangerous fight and, assuming he won, waited for an opportunity to face the Charlo-Castano winner or fought for a vacant title. The WBC ranks Rosario third in the 154-pound division entering their 12-round elimination match.

The 25-year-old Lubin has won five consecutive contests since Charlo knocked him out with one punch in the first round of their October 2017 bout at Barclays Center in Brooklyn. Lubin, then 21, was the mandatory challenger for Charlo’s championship that night.

Most Internet sports books list Lubin as about a 3-1 favorite versus Rosario in Showtime Pay-Per-View’s co-feature.

Baltimore’s Davis (24-0, 23 KOs) will move up two weight classes to face San Antonio’s Barrios (26-0, 17 KOs) for his WBA world super lightweight title in the 12-round main event (9 p.m. EDT; $74.99).
