Mariota struggled mightily Sunday against the Dolphins, completing 21-of-33 passes for 219 yards and a touchdown while throwing two interceptions and losing two fumbles in a 38-10 loss.
Mariota also took a low hit from Dolphins defensive end Olivier Vernon and was noticeably hobbled after the play despite staying in the game. The rookie quarterback has shown his inexperience lately by struggling with ball security. The starting job is still his if healthy, but Mariota has cooled down significantly after opening the season on fire.
