I need your help guys.

I'm writing another listverse article, this time about boxers that went to prison.

I need at least minimum ten, I have got boxers in mind already but I don't want to leave anything out.

Can you guys list fighters that went to prison during their careers, or even just after?
If there is any I don't know I'll research them.

Pretty sure I've got most of the main ones, but help is appreciated.
