Boxer Maxim Dadashev died Tuesday morning at the age of 28 from injuries suffered during his fight against Subriel Matias on Friday.

Dadashev's strength and conditioning coach, Donatas Janusevicius, and his trainer, Buddy McGirt, informed ESPN of Dadashev's death.

McGirt threw in the towel after the 11th round of the bout, and Dadashev later underwent surgery to relieve a subdural hematoma (brain bleeding), which resulted in him being placed in a medically induced coma.

ESPN's Brett Okamoto and Andrew Feldman, as well as boxing promoter Eddie Hearn, commented on Dadashev's death:

Following the fight, Dadashev left the arena on a stretcher and was transported to UM Prince George's Hospital Center in Cheverly, Maryland, per ESPN's Steve Kim.

Dadashev was helped out of the ring and reportedly collapsed and vomited before reaching his dressing room.

Dadashev's manager, Egis Klimas, was informed by neurosurgeon Dr. Mary In-Ping Huang Cobb on Saturday morning that Dadashev was bleeding on the right side of his brain and was "showing signs of severe brain damage," per Kim.

In addition to the surgery, Dadashev was given medication to decrease brain swelling.

Janusevicius said Saturday that Cobb told him the bleeding and swelling had stopped but that Dadashev was in critical condition.

Dadashev, who was a native of St. Petersburg, Russia, owned a professional record of 13-0 prior to the loss to Matias.
