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.

Joey Canoy was scheduled to challenge Oscar Collazo this weekend, but the challenger is currently prohibited from entering the United States.

Puerto Rico’s Collazo has established himself as the man to beat in the minimum division, and his regular activity and lofty ambitions make him a must-see on the 105-pound scene.

Collazo stopped Melvin Jerusalem in May 2023 and has since defended the belt seven times, including a title unification with then-WBA champion Knockout CP Freshmart, also known as Thammanoon Niyomtrong, in November 2024.

Since defeating the Thai champion, Collazo has defended the unified title a total of three times and was scheduled to face Filipino Canoy 25-5-2 (15 KO) on Saturday night.

The duo was scheduled to headline at the Frontwave Arena in California, where standout amateurs Ruslan Abdullaev and Joshua Edwards will also appear on the Golden Boy card.

However, even though the event is just days away, Canoy has not yet been able to travel to the United States due to visa complications and will withdraw from the fight “if he cannot fly to America by Thursday evening,” he claims Daily Tribune.

“As of Monday afternoon, Canoy was still waiting for his U.S. visa to be issued. Sources say that if Canoy cannot fly to America by Thursday evening, he will simply remain in the country.

“The official weigh-in is scheduled for Friday. Canoy’s travel documents were submitted to the U.S. Embassy over three weeks ago.”

Canoy has fought abroad in the past, in both South Africa and Japan, but it is believed that recently tightened US immigration policy combined with a delay in announcing the venue may be to blame for this ongoing problem.

The latest update from WBO president Gustavo Olivieri shows that Canoy indeed missed his shot and was replaced by Mexico’s Luis Castillo.

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.
