Maxim Dadashev’s trainer pleaded with his relentless fighter to stop Friday night’s boxing match, according to heartbreaking video.

Dadashev died Tuesday morning as a result of brain injuries sustained during a 140-pound world title elimination fight against Subriel Matias in Maryland.

Trainer Buddy McGirt confirmed the 28-year-old’s death to ESPN.

“It just makes you realize what type of sport we’re in, man,” McGirt told the outlet. “He did everything right in training, no problems, no nothing. My mind is like really running crazy right now. Like, what could I have done differently? But at the end of the day, everything was fine [in training].”

Matias landed several blows to both Dadashev’s head and body, and after the 11th round McGirt begged Dadashev to stop the fight.

“I’m going to stop it, Max. Max, you’re getting hit too much. If I don’t, the referee’s gonna do it. Come on, Max please,” Buddy McGirt told Damashev after the 11th round before telling the referee to call it.

Dadashev shook his head and indicated he wanted to continue.

“I saw him fading and when he came back to the corner [after the 11th round], my mind was already made up,” McGirt said. “I was just asking him out of respect, but my mind was made up. I wasn’t going to let him go out there.”

Dadashev was eventually removed from the fight, and needed help to get out of the ring before collapsing and vomiting in the dressing room. He was transported to the hospital and underwent emergency brain surgery for two hours to treat a brain bleed, and then was placed in a medically induced coma in an effort to relieve pressure from the right side of his brain.
