The World Boxing Organization has confirmed that Miguel Cotto Promotions and Golden Boy Promotions have formally approached former world title challenger Luis “Flechita” Castillo as a last-minute replacement for Collazo’s WBO minimumweight title defense scheduled for Saturday in California.

Castillo, a 25-year-old Mexican fighter, has a professional record of 22-1-1 with 14 knockouts. However, since the WBO does not currently have a 105-pound weight class, the sanctioning body must first determine whether he can be added to its rankings before approving a championship fight.

In a statement released Tuesday, WBO president Gustavo Olivieri explained that the organization’s Ratings and Championship Committee would meet on Wednesday morning to consider the request.

“The Assessments and Championships Committee will meet tomorrow morning to carefully assess the application, the relevant facts and the athlete’s merits.” Olivieri wrote. “Once the review is completed, the Commission will issue an appropriate ruling.”

Collazo was originally scheduled to defend his WBO title against Canoy in a fight that was considered by many to be one of the most invigorating fights in the minimum weight division. Canoy’s inability to obtain a work visa forced promoters to quickly look for a replacement to keep the champion on the card.

Castillo previously challenged for the 2024 world title, losing a unanimous decision to then-WBA minimumweight champion Knockout CP Freshmart. Since that defeat, the Mexican has gained momentum with several victories that have put him back in the conversation at a global level.

Collazo, 29, unified the WBO and WBA minimum weight titles with a seventh-round victory over Thammanoon Niyomtrong in November 2025. The Puerto Rican southerner is considered one of boxing’s top fighters below the main weight classes and is looking to continue his streak towards further unification fights.

If Castillo is approved by the WBO commission, he will have just a few days to prepare for the biggest opportunity of his career.

Discussing the situation, Simon Jordan questioned whether White’s involvement would actually facilitate get the team over the line.

“Do we think Dana flapping his gums will facilitate in the fight that still seems to be a bit up in the air?” Jordan said on talkSPORT Boxing, debating Fury’s future and the growing influence of Zuffa Boxing.

The broadcaster suggested that the situation is becoming more complicated due to the various parties already involved in the fight, including Riyadh Season, Queensberry and TKO.

Jordan believes the biggest concern is not whether Fury and Joshua want the fight, but whether the business interests surrounding it could delay or derail progress.

“I worry that politics will get in the way of this fight,” Simon said.

Despite concerns that Fury could walk away from longtime promoter Frank Warren, Jordan argued that existing contractual and commercial arrangements could make a neat break impossible.

He suggested that Queensberry could still remain involved behind the scenes, especially if Fury takes a booster fight ahead of his fight with Joshua.

Other panelists asked questions about how the move to Zuffa might impact existing contracts and where the fight will ultimately take place. There has already been speculation that the Fury-Joshua fight could be staged outside the UK, despite previous suggestions that Wembley Stadium would be the preferred destination.

Although Jordan was aware of the growing uncertainty, he did not predict that the fight would end in a fiasco.

“There is too much money in this fight for this not to happen,” Jordan said.

Fury is expected to return for a warm-up at the end of the summer before taking on the fight against Joshua that remains one of the biggest attractions in world boxing.

Jaron Ennis is scheduled to challenge for the unified super welterweight world title this month in hopes of starting an undisputed title run, and Terence Crawford shared whether he believes “Boots” can win all four belts at 154 pounds.

Ennis won both the IBF and WBA welterweight world titles previously held by Crawford, and in October he moved to the super welterweight scene, where He stopped Uisma Lima in the first round announce himself as a threat to the throne.

Now, in his second fight at the weight, Ennis is set to collide with unified WBA and WBO world champion Xander Zayas, and Crawford told Jai McAllister he expects his US compatriot to emerge victorious.

“Man, it’s a tough fight, especially for Xander at this point in his career, but it shows his heart and self-belief. He’s ready to make history for his country and he’ll do really well in this fight.”

“I just think it’s a little too early for him at the moment.”

If Ennis is able to hand Zayas his first career defeat and claim the unified titles, fellow champions Josh Kelly (IBF) and Sebastian Fundora (WBC) will be his next obstacles.

Crawford believes the road to undisputed “Boots” status will likely end with Fundora.

Zayas-Ennis will take place on Saturday, June 27 at the Barclays Center in Modern York. Fundora is coming off a stoppage win over Keith Thurman and is set to make another defense later this year, though no opponent has been named as of this writing.

Kelly is expected to make his first defense of the IBF belt against Belfast’s Caoimhin Agyarko following the Anthony Joshua vs Kristian Prenga card on July 25.
