Maxim Dadashev was hospitalized Friday night following his technical-knockout defeat to Subriel Matias.

According to ESPN’s Bernardo Osuna, doctors determined Dadashev needed to have surgery early Saturday morning to relieve severe swelling on his brain. Russia’s Dadashev, 28, was rushed to UM Prince George’s Hospital Center in Cheverly, Maryland, from MGM National Harbor in nearby Oxon Hill after falling ill as he tried to leave the ring.

An unsteady Dadashev vomited into a bucket as he attempted to leave the ringside area on his own. He was taken from the venue on a stretcher.

Dadashev absorbed a lot of punishing punches from Matias, particularly during the 11th and final round of a fight ESPN televised. Dadashev wanted to continue, but his trainer, Buddy McGirt, threw in the towel once Dadashev came back to his corner after that 11th round.

“I think right now he’s dehydrated,” McGirt told ESPN.com. “I think he really needs some IVs in him. He didn’t want to drink much water in the corner. He kept spitting it out. He had one hell of a fight, tough fight. He took a lot of shots. I think it was time to stop it.”

Dadashev (13-1, 11 KOs) traded inside with Puerto Rico’s Matias during the second half of their scheduled 12-round fight. Matias (14-0, 14 KOs) got the better of Dadashev in those exchanges, hurt his opponent to the body and landed a lot of hard shots during the 11th round of their IBF 140-pound elimination match.

“I hope that Maxim is all right,” Matias said. “He is a great fighter and a warrior.”
