GREEN BAY -- The Packers just can't seem to get healthy at linebacker. Rookie inside LB Blake Martinez will miss his third straight game today in the showdown with Seattle while still recovering from a knee injury.

Martinez was questionable on the injury report coming into the game, and the Packers already had ruled outside LBs Nick Perry (hand) and rookie Kyler Fackrell (hamstring) out. Veteran Clay Matthews is active and will play, but he's still dealing with a shoulder injury that limited him significantly last week.

A key question in this game is, given all the injuries, how the Packers will use Matthews. Will he be needed at inside linebacker, or will Jake Ryan and Joe Thomas hold down the fort there? Will he be needed more at outside linebacker with Perry out? Will he drop into coverage against Seattle TE Jimmy Graham, which was a role he handled well last year in Green Bay's victory over the Seahawks? Last but not least, how many snaps can he play?

Matthews' deployment will be watched closely throughout the day. To read some of his comments to the media this week, click here.

Snowy day: It has been snowing most of the day in Green Bay, with a few inches accumulating in the morning. Since the tarp has been pulled off Lambeau Field, it's still flurrying, but little to none is accumulating on the ground. There is a chance of more snow coming, but the biggest piece of the storm may have already passed.

Temperatures are in the high 20s with wind chills in the low 20s. There's not much wind to speak of and that isn't expected to change.

Around the NFC North: It appears, at the time of this posting, that the Packers will need to win today to stay two games behind first-place Detroit in the division. The Lions are leading the Bears in the second half, but it's close. With a victory, the Lions would improve their record to 9-4.

If the Lions win and the Packers were to lose, the only way for Green Bay to win the division would be to win its final three games with Detroit losing its final three games.

Minnesota, which entered the day tied with Green Bay at 6-6 for second place, is in a tight game in Jacksonville in the second half.
