What happened: Adam Schefter and Ian Rapoport had attributed his expected absence to a back injury. Porter entered Week 1 listed as questionable. [NFL injury tracker](https://www.nfl.com/news/nfl-week-1-injury-report-2026-season)

Why it matters: Pittsburgh must redistribute his cornerback responsibilities against Atlanta. Porter is entering the final year of his rookie contract, with the Steelers’ in-season negotiating freeze limiting the window for an extension.

What to watch: Porter’s participation in the next practice week will be the next availability checkpoint.
