The Green Bay Packers are limping into week three, both literally and figuratively. Cornerback Sam Shields will miss a second-straight game recovering from a concussion and on the doubtful side of the injury list are Clay Matthews, Letroy Guion, Morgan Burnett, Datone Jones and T.J. Lang. Guion is likely most challenged to play after suffering a tear to his MCL against the Minnesota Vikings and with the bye week coming up. The others would all be big losses, mostly to the defense. While the Lions aren't lighting the world on fire, they are playing well offensively under offensive coordinator Jim Bob Cooter and yes, I just wanted to work that name into this piece somehow and it's out of my system now.
