Maxim Dadashev has died from injuries suffered during Friday's fight, according to trainer Buddy McGirt and Donatas Janusevicius, Dadashev's strength and conditioning coach.

Dadashev, 28, had been in UM Prince George's Hospital Center since the 11th-round loss to Subriel Matias. He underwent a two-hour surgery to relieve a subdural hematoma, or bleeding of the brain, and had been in a medically induced coma.

Early Saturday morning, neurosurgeon Mary IH Cobb told Dadashev's manager, Egis Klimas, and Janusevicius that the boxer had suffered a brain bleed on his right side, that his head was shaved and his scalp opened up, and that he was showing signs of severe brain damage. He had been given medication to decrease swelling.

Dadashev, from St. Petersburg, Russia, was 13-1 as a professional boxer.
