context: On Saturday, July 23, 1989, much of America learned of the AFL for an unintended reason, when the Pittsburgh Gladiators' head coach, Joe Haering, made football history by punching commissioner Jim Foster during a game with the Chicago Bruisers. The national media ran with the story, including a photo in USA Today. The game was played between the two teams in Sacramento's Arco Arena, as part of the AFL's 'Barnstorming America' tour. Foster had walked onto the field of play to mediate an altercation between the two teams when Haering, a former NFL assistant, punched him in the jaw. Haering was suspended without pay.
