Tennessee Titans quarterback Marcus Mariota has been ruled out for Sunday against the Dolphins in Miami.
Matt Cassel will get the start, with recently signed Brandon Weeden backing him up.
Mariota injured his hamstring in Tennessee's loss to Houston last Sunday and was considered a game-time decision due to the injury. His recovery time is estimated to be 2-4 weeks, a source told Rapoport.
