All three judges in Dirrell Abraham fight from Michigan!

I thought the rules of the super six stated that the judges had to be from neutral countries

The first round fights all had judges from neutral countries and only the Ward-Kessler match had a hometown ref.

Looks like they decided to ditch the impartiality once the fights didn't go as planned
