Jermell Charlo gave Brian Castano even more credit in the statement he issued Tuesday night on Instagram than he did during their post-fight press conference.

Charlo commended Castano again for how he fought in their 12-round, 154-pound title unification fight, which resulted in a controversial split draw Saturday night at AT&T Center in San Antonio. Houston’s Charlo (34-1-1, 18 KOs) still feels he deserved to win a highly competitive contest Showtime televised, yet he noted Tuesday night that he doesn’t want to become boxing’s undisputed champion in his division by barely beating Argentina’s Castano (17-0-2, 12 KOs).

The 31-year-old Charlo wants a decisive victory over Castano in a rematch both boxers contend that they need.

“Brian Castano is one hell of a better fighter than anyone gave him credit for and he came to fight for his life Saturday,” Charlo wrote on Instagram. “If fights are scored as a whole I landed the harder and better shots, but boxing isn’t scored that way. Boxing is scored round by round. I’ve always said to take a belt from a champion you need to take that belt and the judges felt neither of us did enough to take those other belts and they ruled a draw.

“I don’t want to become undisputed by a narrow controversial decision. I want to make a statement. I didn’t do my part to get the KO and as always I will continue to learn and improve. When we run it back, just like I adjusted in Harrison II, there will be no doubt about the result. #LionsOnly4L”

Charlo knocked out Detroit’s Tony Harrison (28-3-1, 21 KOs) in the 11th round of their rematch and regained his WBC belt in December 2019 at Toyota Arena in Ontario, California. Harrison upset Charlo almost exactly a year earlier by unanimous decision in their 12-rounder at Barclays Center in Brooklyn.

Harrison’s win caused controversy as well.

On Saturday night, Charlo and Castano ferociously fought for Charlo’s IBF, WBA and WBC championships and Castano’s WBO belt. Charlo hurt Castano in the second, 10th and 11th rounds and rallied during the championship rounds to secure a split draw.

New Jersey-based judge Steve Weisfeld scored their fight 114-113 for Castano, who rocked Charlo with a left hook in the third round. Nevada’s Tim Cheatham scored their back-and-forth fight a draw, 114-114.

Puerto Rico’s Nelson Vazquez oddly scored Charlo a 117-111 winner.
