The Tennessee Titans listed quarterback Marcus Mariota as inactive for Sunday's game against the Miami Dolphins and have handed veteran Matt Cassel the start.
Mariota left last week's game against the Houston Texans with a hamstring strain.
Mariota was a limited participant in practice this week, but will instead turn his attention to returning to health for next week's Monday night contest with the Indianapolis Colts.
Cassel filled in for Mariota late in last week's game and went 4-for-10 for 21 yards and two interceptions.
