The scheduled main-event boxing match between Amanda Serrano and Nina Meinke was cancelled on Saturday night, just minutes before it was supposed to happen, it was announced on the card's broadcast.

Serrano suffered an eye injury Friday and was deemed medically unfit to compete by the Puerto Rican Boxing Commission, according to event promoter Most Valuable Promotions (MVP).

The event was billed as Serrano's homecoming, her first time fighting on her home island since becoming undisputed featherweight champion. MVP announced during the event that everyone who paid for tickets to the show would get a 100% refund and Meinke would be paid her full purse.

Serrano appeared in the ring to address the fans and was very emotional. She apologized and said she would one day have her retirement fight in Puerto Rico.

"I wanted to fight in front of my people," Serrano said.

Jake Paul, Serrano's promoter, won in the co-main event, knocking out Ryan Bourland in the first round. He said Serrano's cornea was exposed and it would have been extremely risky for her to compete. Paul said the injury happened 36 hours prior and MVP and Serrano were working to be able to get her ready to fight since then.

"I'm absolutely gutted," Meinke said. "We all wanted this fight -- I wanted this fight. Puerto Rico wanted this fight. I really hope we can make this happen again."

WBO president Francisco "Paco" Valcarcel said his sanctioning body will not strip Serrano of her title. Meinke, he said, will remain the mandatory challenger.

"She wanted to fight, but the doctor didn't allow her to fight, because of the problem in the left eye," Valcarcel said. "I assume the fight will be rescheduled and we will sanction the fight."
