Antonio Brown's tenure as owner of the Albany Empire has hit an all-time low -- the ex-NFL star's team was just kicked out of the National Arena League.
The organization announced the decision on Thursday ... saying Brown repeatedly failed to pay his team's monthly assessments, which are used to support the league's operating budget.
In a statement, the NAL explained the Empire made its first assessment payment in April, but it was later challenged. The Super Bowl champ's team then refused to cough up the money in May.
