What happened: Cowboys defensive coordinator Christian Parker is scheduled to speak to media tomorrow at The Star. The session is expected to , a timeline for getting him into the lineup and how his arrival affects the rotation.

Why it matters: Dallas has already played 12 defensive backs through three games entering Week 4, underscoring instability in the secondary. Adding a starting-caliber corner would reshape snaps for the back end as Christian Parker tries to settle combinations. The move follows days of trade discussion around Porter involving Dallas and Pittsburgh.

What to watch: Watch for Parker's read on Porter's readiness and first practice work, plus any clarity on who starts opposite him.
