Subriel Matias has indicated to NBC News that he's "devastated" over the death of Maxim Dadashev, 28-years-old.

Dadashev died Tuesday after suffering a brain injury in last Friday's fight with Matias at the MGM National Harbor in Oxon Hill, Maryland.

"No one is prepared to die while looking for dreams and goals. We simply go up to the ring thinking about the well-being for our family without knowing how complicated and difficult it is to get into the ring. Fly high great warrior. Only God knows the reason of things. You will always have my respects. RIP Maxim Dadashev," Matias stated.

The fight, showcased by ESPN and sanctioned as an IBF junior welterweight eliminator, was stopped after the conclusion of the eleventh round, after trainer Buddy McGirt felt Dadashev had taken too much punishment.

"I don't want this check. Those were his first words," spokesman Fernando Gaztambide recalled about Matias.

As he left the ring, Dadashev was unable to properly walk and needed help from several of his team members. He began to vomit when paramedics placed him on a stretcher - and he was quickly rushed to a local hospital.

Doctors discovered that he suffered severe brain damage. Surgery was performance and afterwards he was placed in a medically induced coma. The injuries were too much for his body to handle.

"He was a very kind person who fought until the very end," Dadashev's wife, Elizaveta Apushkina, said in a statement issued by Prince George's Hospital Center. "Our son will continue [to] be raised to be a great man like his father."

After the fight, Matias flew home to the seaside region of Catano, outside San Juan, and he's been holed up in his apartment with his girlfriend and promoter, Gaztambide told NBC News.
