GREEN BAY-(WFRV) The Green Bay Fire Marshall is investigating the cause of an early morning fire that caused heavy fire and smoke damage to Preble High School's gymnasium. The gym is closed until further notice. But won't affect the opening day for the new school year on September 2. The varsity and junior varsity football squad have to deal with smaller, temporary offices and locker facilities and damaged equipment. We have team coverage from Local 5's Terry Kovarik and Wendy Fleury.
