What happened: DeMeco Ryans said Monday the linebacker injured his shoulder in Houston's 36-31 loss to Buffalo. The Texans have not yet decided whether to place Henry To'oTo'o on injured reserve.

Why it matters: Houston now heads into its next home game with a new hole in the middle of the defense. The setback lands alongside a close loss and adds another personnel decision for a team trying to steady itself early in the season.

What to watch: Houston's next injury report and any roster move on To'oTo'o will be the key follow-up. The Texans are set to host Cincinnati next.
