What happened: Pittsburgh failed to reach a long-term extension with Joey Porter Jr. before the season, and the cornerback has moved deeper into trade chatter. Kansas City entered that conversation after rookie Mansoor Delane left Monday night's game with a shoulder injury.

Why it matters: Delane's injury adds urgency for a Chiefs secondary that is suddenly weighing outside help. Detroit's earlier inquiry on Porter suggests Kansas City would be stepping into an active market, not starting one.

What to watch: Porter's practice participation should sharpen whether he stays on Pittsburgh's Week 2 track or becomes a live trade option. Kansas City's next roster move will draw more attention if Delane's shoulder issue carries into the week.
