Classic Ironhead indeed 👍 His long TD run against the Raiders was in 1988. Was his first NFL TD. The OP’s posted game was three years later, the next time the AFC West came up in the rotation for the old NFC West teams.
I was at the Falcons game in ‘92, on a Thursday night (back when that kind of thing was rare) when he trucked Falcons DB Scott Case. That’s included in your posted video.
Ironhead was a bit like Muncie — addiction kept him from being great on a consistent basis. His son has had quite the career, though.
