What happened: Dallas completed its trade for Joey Porter Jr. and ruled him out for Thursday. The club is optimistic he can get on the field quickly, with Sunday as his first chance to debut.

Why it matters: The move targets a secondary that has already pushed Dallas through 12 defensive backs in three games. With two games in five days, adding another outside corner gives the defense a chance to stabilize its coverage rotation.

What to watch: The next checkpoint is whether Porter is active Sunday and how much work he handles right away. That usage will show how quickly Dallas plans to fold him into the secondary.
