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, TMZ Sports has learned.
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.
