Boxer Maxim Dadashev Dead at 28 after Fight :(

4:01 PM PT -- The wife of Maxim Dadashev, Elizaveta Apushkina, released a statement to ESPN's Steve Kim, saying ... "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 be 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.”

Maxim Dadashev -- the boxer who went into a coma after suffering injuries during a fight Friday night -- has died, both his trainer and coach announced Tuesday.

He was 28 years old.

Dadashev, a Russian junior welterweight contender, was fighting Puerto Rico’s Subriel Matiasin the co-main event of Top Rank's boxing card on ESPN last week, when things took a horrible turn in the later rounds.

Dadashev was taking a lot of punches to the face and head ... and it got so ugly, his trainer, Buddy McGirt, had to beg the boxer to throw in the towel.
