The investigation continues into how a worker at Acrisure Stadium fell about 50 feet from the scoreboard.
He was taken to Allegheny General Hospital and last reported to be in critical condition.
The accident happened while crews were setting up for the Sunday Night Football TV broadcast on Saturday night.
The man fell from the scoreboard to a catwalk area.
First responders were able to locate the man and load him into a Stokes basket, before he was lowered down and taken to the hospital in an ambulance.
Pittsburgh Public Safety says the victim suffered “severe” injured to his “lower extremities.”
