Jermell Charlo has grown tired of what Tim Tszyu has said about him while Charlo’s left hand heals.

The undisputed junior middleweight champion promised to make Tszyu pay for that trash talk once their title fight is finally rescheduled. Charlo predicted that he’ll knock out Tszyu when the IBF/WBA/WBC/WBO 154-pound champion took to Instagram Live on Saturday night from the backyard of his home.

“Hey, when they release me [to fight], I’m knockin’ that bitch out from Australia,” Charlo said in reference to Tszyu. “And I ain’t gonna say nothin’ else. And this motherf----- can run his mouth, talk. He gotta get confirmation from all the motherf----- that you fought somebody because, you know, like I’ve done my due diligence in the world of boxing.

“At 154, I’m the king. I been the king. I’m the king. You gotta go try to, you know what Tony Harrison told you, you know, you got this staircase over here. You know, keep feeling yourself. We’ll get there. When I do fight you, bitch, it’s over. I don’t play that sh!t.”

Tszyu chastised Charlo for being “drunk off his head” when Charlo sat ringside for the Gervonta Davis-Ryan Garcia fight April 22 at T-Mobile Arena in Las Vegas (

Charlo, 33, didn’t indicate in the abovementioned video when he’ll be medically cleared for full training. Tszyu, 28, is scheduled to remain busy June 18, when he’ll fight for the second time in barely three months.

Sydney’s Tszyu (22-0, 16 KOs) will make the first defense of his WBO interim junior middleweight title against Mexico’s Carlos Ocampo (35-2, 23 KOs) in a 12-round main event Showtime will televise from Gold Coast Convention and Exhibition Centre in Broadbeach, Australia. Tszyu needed surgery recently to treat a dog bite to his right forearm, but he will still oppose Ocampo on their scheduled date.

Tszyu won his interim title by stopping former WBC champ Tony Harrison (29-4-1, 21 KOs) in the ninth round March 12 at Quodos Bank Arena in Sydney. Tszyu dominated Detroit’s Harrison, who is the only opponent to beat Charlo in the Houston native’s 15-year professional career.

Charlo (35-1-1, 19 KOs) hasn’t fought in more than a year, not since he knocked out Argentina’s Brian Castano (17-1-2, 12 KOs) in the eighth round of their rematch in May 2022 at Dignity Health Sports Park in Carson, California. His win against Castano, who was the WBO champ entering their second bout, made Charlo boxing’s first fully unified 154-pound champion of the four-belt era.

Charlo was scheduled to defend his four titles against Tszyu, the mandatory challenger for his WBO belt, on January 28 at Mandalay Bay Resort and Casino’s Michelob ULTRA Arena in Las Vegas. Their fight was postponed indefinitely because Charlo suffered a fracture to his left hand while sparring a few days before Christmas.

Charlo stated during Showtime’s broadcast of the Tszyu-Harrison bout that he expected his fight with Tszyu to be rescheduled for late this summer, but his hand injury has taken longer to heal than expected.
