What did Gary Antonio Russel do to piss off the injuns?

Jun 6, 2013
I was just checking to see how my favorite prospects did in 2020, and Boxrec says that Russel has been
"suspended by The Mohegan Tribe, Dept pf Athletic Regulation, indefinitely."
His last bout was there, but he won it fairly IIRC.

Did he not pay his bar bill or something?
