GREEN BAY -- It's December football indeed.

Mike McCarthy has used that phrase all week long, and the weather has announced it as much as the calendar. It's snowing pregame at Lambeau Field, and 1 to 3 inches of accumulation are possible throughout today's game against the Houston Texans.

The snow is not heavy, but it's expected to be steady throughout the game, tapering off in the late afternoon or evening. Temperatures will be in the low 30s, so not all the snow will stay, but the weather will definitely be a factor in an important game for both teams.

The last time Houston came to Lambeau Field, back in 2008, the weather was a big story, too. It was just 3 degrees at kickoff that early December day, one of the coldest regular-season games in Green Bay history.

Injury update: As expected, QB Aaron Rodgers and LB Clay Matthews are active and expected to play after being listed as questionable on the final injury report.

LB Jake Ryan is back for the Packers and active today after missing basically the last three games with an ankle injury. LB Blake Martinez (knee) remains out for the second straight week, though.

What that means for Matthews remains to be seen. Matthews filled in at inside linebacker last week with both Ryan and Martinez out, but with Houston RB Lamar Miller expected to be the focal point of the Texans' offense, it's not a given that Ryan's return will send Matthews back outside. He could play a combination inside-outside role today, depending on down-and-distance situations.

CB Damarious Randall (groin) who was added to the injury report on Saturday as questionable, is active and expected to play. His availability has landed new CB Makinton Dorleant on the inactive list today.
