A weekly look at what the Green Bay Packers must fix:

If the Packers' defense couldn't stop Miami Dolphins quarterback Ryan Tannehill on the read-option plays last Sunday, imagine what Cam Newton might do this week when his Carolina Panthers come to Lambeau Field.

Tannehill ran the read-option to perfection on his 40-yard scamper in the third quarter. On a second-and-5 play, Tannehill sucked in linebacker Clay Matthews, who played it as if Tannehill was going to hand the ball off to running back Knowshon Moreno. But when Tannehill saw that he could beat Matthews to the edge, he kept the ball and ran around left end. He might have scored had safety Micah Hyde not tracked him down from behind.

That would not be the last time the Dolphins fooled the Packers with the read-option on Sunday. On a fourth-quarter play, Matthews got up the field to play Tannehill, who instead handed the ball off to running back Lamar Miller, who ran up the middle for 9 yards.

"We'll go back to work and get that cleaned up," Packers defensive coordinator Dom Capers said. "We know we're going to see that with an athletic quarterback coming in this week who ran for over 100 yards and threw the ball for a bunch of yards."

Newton had his best rushing performance of the season in Sunday's tie with the Cincinnati Bengals. The Panthers quarterback rushed for 107 yards on 17 carries, several of them on read-option plays or designed runs.

The read-option has baffled the Packers before, going back to Colin Kaepernick's liberal use of it during the San Francisco 49ers' playoff victory over the Packers in January 2013.

"We're going to get a similar attack with an athletic guy like Cam Newton," Capers said.
