Russian boxer Maxim Dadashev (13-1, 11 KOs) has succumbed to injuries he suffered in his IBF junior welterweight #1 contender bout with Subriel Matias (14-0, 14 KOs) on Friday night.

Trainer Buddy McGirt and coach Donatas Janusevicius confirmed that Dadashev passed away at the UM Prince George’s Hospital Center in Cheverly, Maryland, where he was transported after the fight in nearby Oxon Hill.

Dadashev lost to Matias by 11th round TKO, absorbing 260 power punches from his opponent. It was McGirt who made the decision to throw in the towel after the 11th round, which was the clearest and most lopsided round of the contest. Matias was up on all three scorecards at the time of the stoppage.

Dadashev was a promising prospect with a deep amateur background, compiling a record of 281-20. He turned professional in 2016 and was signed by Top Rank Boxing. Dadashev quickly went from rising prospect to a contender, defeating the likes of Darleys Perez and Antonio DeMarco on his way to an IBF title eliminator vs. Matias.
