I want to know the answer to the following question:
In what arena were the Gladiators playing the Bruisers on July 23, 1989?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: no
