The undercard to Logan Paul's exhibition bout with Floyd Mayweather has lost one of its bouts after a fighter flew home hours before he was due in the ring.
Adam Ramirez was due to take on 18-year-old Micky Scala over four rounds in Miami.
But Scala took to social media to reveal Ramirez had taken a plane out of Florida, leaving him without an opponent.
"My opponent is a coward got on a plane this morning and left Florida," he wrote. "No fight tonight. Took a big platform and opportunity from me."
Scala was due to fight for just the third time in the paid ranks having turned professional with Mayweather Promotions when he was just 16.
Ramirez has won one and lost the other of his two professional fights so far but has not fought for 18 months.
Both men weighed in on Friday with Ramirez scaling almost 10lb heavier than Scala.
Paul will face Mayweather in the main event tonight over eight rounds in a so-called exhibition bout.
No winner will be announced but knockouts will be permitted and the referee will be able to stop the fight.
But while the main event may be a monumental mismatch, there are some legitimate fights on the undercard, as well as a bizarre exhibition between former NFL star Chad 'Ochocinco' Johnson and bareknuckle fighter Brian Maxwell.
Former super-welterweight champion Jarrett Hurd faces the returning Luis Arias, whose last opponent Luke Keeler earned a world title shot by beating the American.
And Badou Jack, who was scheduled to rematch Jean Pascal for the light heavyweight title before Pascal failed a drug test, will face undefeated Dervin Colina.
Hurd insisted this week that he is ready to remind his rivals of his talent.
“Everyone knows I have unfinished business at 154lb," he said. "I’m not looking past Arias though; this fight is just a stop at middleweight because I’m going back down to take care of that business.
“We’ve had an amazing training camp with my new trainer Kay Koroma in Colorado Springs. I have a chip on my shoulder. I think a lot of people forgot who I was. I had the best resume in the weight class. Come Sunday, I’m going to remind everyone who I am.
“It’s always strictly business and it’ll be the same on Sunday. Arias is obsessed with my weight and thinks I’m struggling. But he needs to focus on what he needs to do on Sunday night.
“I’ve been boxing for 15 years now and coach Koroma just helped me evolve the things I already knew. He’s got me not just coming forward and using my strength, but moving around and boxing a little bit.”
