Evander Holyfield is staring down some jail time if he doesn't cough up more than $300k in unpaid child support, TMZ has learned.
The GA. Dept. of Human Services has gone to court on behalf of Evander's 18-year-old daughter Emani Holyfield ... claiming the former champ hasn't paid a dime of court ordered child support since April 2010, and his tab is now $372,097.40.
The DHS is fed up with the waiting game ... so it's asking a judge to lock up Holyfield and garnish his wages until he antes up the back support.
