What happened: Running back Audric Estime is out with a thigh injury. Hamstring injuries will also sideline tight end Oscar Delp and defensive end Cam Jordan.

Why it matters: The absences reduce the New Orleans Saints' options on both sides of the ball to start the season. Their backfield could be further depleted if Kamara cannot play.

What to watch: Kamara's availability comes down to a game-time decision Sunday.
