What happened: Marcus Mariota moves into the Week 4 quarterback role against the Indianapolis Colts after Jayden Daniels was ruled out. Daniels had been listed as questionable before the change in status.

Why it matters: The switch matters because it changes the Week 4 plan at quarterback and puts the offense in Mariota's hands against Indianapolis. It also extends a run of late-September attention on Daniels' availability, with Mariota already tied to recent fill-in duty.

What to watch: Next up is how Mariota is deployed against Indianapolis and when Daniels' status changes again after Week 4.
