What happened: Porter carried no injury designation into Week 4 after joining Dallas, putting the corner on track for his first game action of 2026 against Houston. The Cowboys traded for him this week as they reshaped a secondary that has been forced to lean on its depth early.

Why it matters: Dallas has already used 12 defensive backs in three games, so Porter's availability could quickly affect the rotation on the outside. The move also fits Jerry Jones' win-now framing after the Cowboys spent future draft capital to get help at corner.

What to watch: Sunday's inactive list will show whether Dallas clears Porter for a full debut or eases him into the mix. His snap count against Houston should offer the first clue about how quickly the Cowboys plan to use him.
