Crabtree leads all of the game's receivers with four catches for 42 yards and two touchdowns. Smith has been efficient in the first half, connecting on 14-of-15 passes for 146 yards and two touchdowns.
Arizona has struggled mightily on offense, and has just 42 total yards. The 49ers' vaunted run defense has lived up to its top billing and nearly held the Cardinals to negative yardage in the first half as running back LaRod Stephens-Howling carried the ball seven times for 6 yards on the ground.
The Cardinals will receive the ball to begin the second half.
