What happened: Jayden Daniels has been ruled out for Sunday's game against the Indianapolis Colts with an elbow injury. Marcus Mariota is set to start after Dan Quinn confirmed the decision Friday.

Why it matters: The move settles the quarterback plan for Sunday after Daniels carried a questionable tag earlier in the week. It also sets up Mariota for another start against Indianapolis as Daniels remains sidelined.

What to watch: Daniels' next injury designation after Sunday's game will be the next marker on his return. Mariota now gets the closing stretch of prep for the Colts matchup.
