What happened: Cole Christiansen and Marcus Harris are now available for Sunday night after the standard elevation move. Christiansen was listed at linebacker and Harris at defensive tackle in the transaction.

Why it matters: The move gives Kansas City extra front-seven depth on game day. Harris has already been part of September roster churn, with a Sept. 14 elevation preceding this weekend's activation.

What to watch: Final inactive lists before kickoff will show whether both defenders dress. Their snap counts will clarify whether the move was aimed at special teams depth, defensive rotation help or both.
