Boxing often gives fans a big show, more so when it comes to knockouts. Anthony Joshua destroying Jake Paul a couple of months ago could be the more famous recent example of that.

It is normal to see stars suffering that fate, but when it comes to newcomers, it is hard to see them take punishment. On Saturday, Jocelyn Camarillo recorded a dominant win over 19-year-old Isis Sio.

With 48 seconds left in the first round, Camarillo landed a big left hand in Sio’s face. She landed three more hits before her opponent fell to the ground and the referee stopped the fight. Sio wasn’t in the best shape after that, and the aftermath turned more dramatic.

Vinny’s Corner reported that Sio was in the Intensive Care Unit at Loma Linda Medical following the fight.

Supreme Boxing on Instagram added that Sio suffered a knockout on January 30, during a fight against Perla Bazualda. Giving her another chance to fight so quickly proved to be a bad decision.

Isis Sio made history in 2025

In August 2025, Isis Sio prepared for her first professional fight. She became the first pro boxer from North Dakota to compete in North Dakota since Mariah Prussia in March 2019. At the time of writing, she holds a 1-3-0 professional record.

Sio lost to Jessica Radtke Maltez via unanimous decision in her first fight. She bounced back with a UD win over Katelyn Radtka before losing back-to-back fights via knockout.

Dana White has shut down the idea of UFC stars stepping into boxing, making it clear that fighters like Ilia Topuria will remain inside the promotion’s structure.

The topic has resurfaced amid growing crossover interest, but the UFC president has taken a firm and familiar stance.

His comments leave little room for interpretation about where the promotion stands.

Dana White boxing stance on Ilia Topuria crossover fights

Dana White rejected boxing fights when asked about the possibility of UFC stars like Ilia Topuria stepping into crossover bouts.

“No. No way in h___. The crossover fights suck, that’s not what we do. I wanna see the best fighters in the world fight the best fighters in the world,” White said.

The response underlines a consistent philosophy, with White focused on maintaining competitive integrity inside MMA rather than chasing novelty events.

It also signals that even rising names like Topuria will be kept within the UFC system rather than diverted into one-off spectacles.

Dana White explains why UFC avoids crossover boxing fights

Dana White expanded on his position by pointing to past experience and questioning the long-term appeal of crossover boxing events.

“There are other networks and other people who do that s___. It’s not what I do,” White continued.

He concluded, stating: “I did it once. Well, I don’t know if it’s amazing, it was financially unbelievable, but how many times can you keep fooling people with that?”

The reference reflects on previous crossover success financially, while also highlighting concerns about sustainability and authenticity.

For White, the priority remains building matchups within the UFC, where rankings and competition carry more weight than spectacle.

Last weekend Mike Tyson conspicuously wore a cast on his right arm the Mike Tyson Invitational, a three-day amateur boxing event. Naturally, that has fueled some doubt about his exhibition fight scheduled with Floyd Mayweather Jr. for April 25 in the Democratic Republic of Congo.

This week, during Tyson’s trip to Thailand, there was no sign of the cast in videos and photos of Tyson. So what does it all mean?

Let’s start with Tyson’s interview on "The Ariel Helwani Show" on March 11. Tyson, 59, said he injured himself boxing.

“Training, punching stuff,’’ Tyson said. “Just a little sprain, I have to go hard, it’s the only way I’ve got to go.’’

Initially, Tyson seemed to suggest the fight take place as planned. But when Helwani asked if the injury would affect the exhibition, Tyson replied, “We'll see.’’

A representative for Tyson did not immediately respond to a request for information about Tyson's injury and the fight.

CSI Sports, the group that announced the fight in September, did not immediately respond to a USA TODAY Sports request for comment.

This may conjure up memories of the ulcer flare-up Tyson had that postponed his fight with Jake Paul for four months. And remember, the erstwhile Baddest Man on the Planet will turn 60 in June.

Tyson vs Mayweather: What else is up on the air?

Longtime boxing writer Dan Rafael reported early this month that the fight still is in the works but it won’t take place April 25 and might not be held in the Congo.

“Been much discussion about the Mike Tyson – Floyd Mayweather exhibition taking place April 25 in Congo,” Rafael wrote, according to SB Nation. “But, per source with knowledge of the plans, it definitely won’t be that date. It will move to a later date and while it might be in Congo, no site is set.”

CSI Sports, the group that announced the fight, still has the original information on its website – that includes no date.

Tyson-Mayweather fight: What do we know for sure?

The men agreed to fight. Well, according to a news release.

The announcement of the proposed fight came by news release issued in September. Since then, Tyson has reaffirmed his commitment to fight, said there won't be a weight limit and said the fight is scheduled for eight rounds. But Mayweather has made no such public proclamations.

Meanwhile, Mayweather has committed to a rematch with Manny Pacquiao Sept. 19 at The Sphere in Las Vegas, according to a news release issued in February by Netflix, which plans to livestream the fight.
