What happened: Porter was ruled out for Thursday's game before Dallas completed its trade, and Adam Schefter reported he is now poised to make his 2026 season debut Sunday. Field Yates captured the turnaround with a line about a bad back after the move.

Why it matters: Dallas gave up a 2028 second-round pick and a 2027 sixth-round pick to get Porter, so a quick debut would put the deal on the field right away. The Cowboys have already used 12 defensive backs in three games, making added depth in the secondary an immediate roster issue.

What to watch: The next checkpoint is Dallas' final game-status decision for Sunday and whether Porter is active after missing Thursday. His workload, if he dresses, will show how quickly the Cowboys want him in the rotation.
