What happened: McDonald missed the last two days of practice with an ankle injury, according to James Palmer. [Houston Chronicle](https://www.houstonchronicle.com/sports/texans/article/kayden-mcdonald-injured-reserve-injury-22427774.php)

Why it matters: Houston selected the defensive tackle No. 36 in April's draft. His absence leaves the remaining interior defenders to handle the opening stretch of the season.

What to watch: Watch how Houston distributes snaps at defensive tackle and whether McDonald resumes practice when eligible.
