What happened: Darnold's glute injury will keep Seattle's starting quarterback off the field Sunday against Arizona. Seattle is not preparing an injured-reserve move at this point, leaving his roster status unchanged for now.

Why it matters: That pushes the Seahawks' Week 2 quarterback plan from uncertainty into a firm game-day absence against the Cardinals. It also keeps open the possibility of a shorter-term roster disruption even after Darnold was previously expected to miss 4-6 weeks.

What to watch: Seattle's next injury report will show whether the club keeps Darnold on the active roster into Week 3. Sunday's replacement plan at quarterback is now the immediate follow-up.
