What happened: Linebacker Kenneth Murray is scheduled to play Sunday against the Dallas Cowboys. The roster addition arrives as starting linebacker Azeez Al-Shaair is officially sidelined for the matchup.

Why it matters: The transaction introduces an experienced presence to compensate for the loss of a core starter. Dallas, currently managing its own secondary adjustments following a recent trade for cornerback Joey Porter Jr., will encounter a different opposing front seven than initially anticipated.

What to watch: Watch how the Cowboys attack the middle of the field against a reshuffled linebacker rotation in the opening half.
