Russian Boxer Maxim Dadashev, who sustained serious brain trauma during a match Friday night that also marked his first professional defeat, later died as a result of the injuries, multiple outlets reported Tuesday. He was 28.

Dadashev was placed in a medically induced coma following a 2-hour surgery early Saturday morning during which a portion of his skull was removed to reduce swelling caused by a brain bleed, ESPN reported.

Dadashev’s doctors reportedly informed his team that he was showing signs of severe brain damage, but cautioned the full extent of the injuries couldn’t be assessed until the swelling subsided.

On Tuesday, Dadashev’s trainer, Buddy McGirt, and his strength and conditioning coach, Donatas Janusevicius, told ESPN the young boxing pro had died.

Dadashev's wife, Elizaveta Apushkina, said: “It is with great sadness that I confirm the passing of my husband, Maxim Dadashev. He was a very kind person who fought until the very end. Our son will continue [being] raised to be a great man like his father. Lastly, I would like to thank everyone that cared for Maxim during his final days. I ask that everyone please respect our privacy during this very difficult time.”                                          

The formerly undefeated boxer from St. Petersburg lost to Puerto Rico's Subriel Matias, 27, Friday night in the 11th round of an IBF junior welterweight world title eliminator match.
