The woman who appeared to start the violent altercation at the Steelers vs. Lions preseason game in August has been hit with a criminal citation.

A spokesperson for the Pittsburgh Police Dept. tells us after launching an investigation into the Aug. 21 melee … cops cited the woman for disorderly conduct.

Per the spokesperson, the woman will likely now have to pay a fine as a result of the ticket.

The spokesperson added that no other citations or charges have been handed out as a result of the fight … though a probe is still ongoing.

As we previously reported, the fight happened at some point during the Steelers’ win over Detroit at Heinz Field … and, as you can see in the footage shot by a bystander, it was chaotic.

The clip shows the woman getting in the face of a man seated one row in front of her … before she eventually slapped him.

The physical touch set the guy off — ’cause you can see in the video, he then swung on both her and the man sitting next to her.

It’s unclear what started the whole thing … but, fortunately, other fans were able to separate the combatants before things got even worse.

Fighting has been a real issue at NFL games this season … ’cause just a few days ago several Rams and Bears fans got into a huge fracas in SoFi Stadium — though it’s not clear if law enforcement was involved in that case.
