He lost his unbeaten record to David Light in December 2022 and followed it with another defeat at the hands of Soslan Asbarov in March 2023.

Jai Opetaia has ruled out a move to heavyweight in the near future as he insists his goal is to still pick up the four cruiserweight belts — of which he currently has zero.

The IBF cruiserweight title won’t be on the line tonight because the IBF announced Friday that it had withdrawn sanction for Jai Opetaia’s voluntary defense against Brandon Glanton.
After the fight was announced, there were weeks of uncertainty on whether the IBF championship would be on the line.
On fight week, the IBF initially granted sanction to the bout after being assured by Opetaia’s team that any belt awarded by Zuffa tonight would be “characterized as a trophy or token of recognition.”
Zuffa Boxing, a promoter, is not allowed to have its own world championship because of the current Ali Act rules, and the Zuffa championship tonight is merely a “trophy.”
At the final press conference for Opetaia vs. Glanton on Friday, however, it was announced that the Zuffa world cruiserweight title would be on the line, and it was treated like a world title, forcing the IBF to withdraw sanction of the bout.
With the IBF withdrawing sanction of tonight’s Opetaia vs. Glanton bout, Opetaia will be stripped of his cruiserweight title when he steps into the ring to face Glanton in his Zuffa Boxing debut.
It’s a huge blow for Opetaia, who has repeatedly insisted his goal in boxing is to pick up the four traditional belts and become the undisputed champion at cruiserweight.
It had come as a shock when the Australian signed with Zuffa, because Zuffa said it would not recognize boxing’s four sanctioning bodies, and Opetaia’s goals were clear.
Opetaia insisted that he would still be able to chase his dreams under Zuffa, which obviously now looks a long way from reality.

Saracho was told that he needs a knockout in the corner. The referee told him that he needed to show him something. This round, one way or the other, is make or break. Salas is putting together a barrage of shots. The referee tells Saracho again, “You’ve got to show me something.” Saracho isn’t showing enough, as Salas gets through with another combination. Finally, Saracho puts together some punches. Nice body shot, left uppercut two-piece from Salas. He is stylin’ on Saracho now. Saracho backs up voluntarily. He looks to be hurt. Nice two-piece from Salas — and now it’s over! Good stoppage.

HUGE right hand from Salas to begin Round 7. Now, he’s going for the finish, and the referee is just starting to take a closer look. It’s not been one-way traffic, but one guy is clearly much more heavy-handed than the other and is putting a bit of a beating on Saracho, but Saracho is doing just enough to stay in the fight. Salas has a 68-16 punch advantage in the last 3 rounds — it’s a 5-6 punch combination from Salas vs. one or two shots from Saracho, who is a beaten man.
10-9 Salas, 69-64 Salas

Heading into the second half of this one. Round 5 was another one for Salas. Saracho’s corner tried to relay the message to him that he was behind through five rounds. Nice pair of rights from Salas while Saracho was backed up. Now, Salas is putting his shots together. Saracho is hurt; he is being hammered to the body, and Saracho looks to be frozen. Big moment in this fight for Salas. More body work from Salas, followed by a right hand on the inside. Dominant frame for Salas.
10-9 Salas, 59-55 Salas
