Ryan Tannehill's return from his knee injury is uncertain, but an MRI showed no structural damage.

The Miami Dolphins will start Matt Moore until Tannehill returns.

"The majority of my career, I've been a backup," Moore said. "I just prepare and know that the opportunity can come at any time. When you get in there, manage the game, don't turn the ball over, but at the same time take your shots and make big plays. That's just how I approach it."
