Starting left guard Daryn Colledge has a stiff lower back, which could mean a rare change on Green Bay's line.
"I always feel like I can be out there and make it," Colledge said. "But they're not going to go off of a player's decision. Emotionally, I want to be there for my guys, and I want to be able to play, but for them, it's a real decision to make, and they've got to make that."
"Spitz had more practice time this week and practiced well," Colledge said. "If they feel he's more prepared and physically ready for the game, then they'll make that decision. If they believe I'm ready to go, then I'll ride it till the wheels fall off."
Colledge has played in 75 consecutive games since his rookie season in 2006. The streak was in jeopardy earlier this season when Colledge suffered a knee injury during a collision with nose tackle B.J. Raji on the practice field. Colledge missed one day of practice, but he made a quick recovery and started in the Packers' 20-17 loss to the Chicago Bears.
McCarthy said a determination on Colledge's playing status won't be made until Saturday.
"I think anytime you have an injury and a player comes off of not practicing and then practicing, it's really the next day is the true indication," McCarthy said. "Knowing Daryn's history, I anticipate that he will go."
The Packers have made only one change to the starting five on their offensive line with the season halfway complete. That happened after four games, when Bryan Bulaga, this year's first-round draft pick, took over at right tackle for veteran Mark Tauscher, who suffered a shoulder sprain and isn't fully recovered.
"I think the biggest difference between this year and last year is we haven't had to move guys around too much, we're able to keep guys in the same spots," Rodgers said.
Notes: Rodgers (ankle), LB Clay Matthews (shin), DE Cullen Jenkins (calf) and LT Chad Clifton (hamstring/knee) also are probable to play Sunday, the Packers' last game before their bye week. Rodgers was a full participant in practice every day after he twisted his left ankle late during the shutout win over the New York Jets on Sunday. The team played it safe with Matthews, who has an NFL-high 9.5 sacks, and didn't have him practice much this week. "He'll be ready to go Sunday," McCarthy said. ... DE Ryan Pickett (ankle) is questionable, but he felt optimistic after going through all portions of Friday's practice that he will be able to play after missing the last game. ... McCarthy said rookie TE Andrew Quarless (shoulder) had a setback after trying to practice Thursday, and the team listed him as questionable. If Quarless can't play, the Packers will be down to Donald Lee and Tom Crabtree at tight end.
