What happened: Porter remains on the PUP list after a back issue flared during a mobility test at the start of camp. Mike McCarthy said his first-year staff wants the opportunity to work with the cornerback.

Why it matters: Pittsburgh's season opener is less than three weeks away, tightening the window for a resolution. Trade interest in Porter surfaced three days before McCarthy disclosed the deadlock.

What to watch: Watch whether negotiations resume and when Porter returns to practice.
