Claressa Shields' brother has been charged for the violent attack on Ivana Habazin's trainer at their fight weigh-in earlier this month ... and he's now facing a possible 10 years behind bars for the crime.
As we previously reported, 68-year-old James Ali Bashir was snuck up on and socked in the face at the Shields-Habazin weigh-in on Oct. 4 in Flint, Michigan after things got testy during the fight's promotion.
Bashir was seriously injured -- he was taken from the arena to the hospital and required surgery -- and the whole altercation caused the mega-boxing match to be canceled.
