Left tackle Chad Clifton, who exited last week's game against Detroit with an injured hamstring, was limited at practice on Thursday. He did not take part in any of the 11-on-11 work.
"We'll probably take the week. I'm not sure if Chad will go this week," McCarthy said.
The Packers, winners of three consecutive games, started the same five players up front against San Francisco and Detroit. But, barring Clifton making a quick recovery, the Packers won't be able to run out the same starting quintet for the first time this season. With Clifton joining right tackle Mark Tauscher, guards Daryn Colledge and Josh Sitton and center Scott Wells, the Packers have allowed only three sacks while scoring 64 points over the last two weeks.
Rookie T.J. Lang would get the start in place of Clifton. Lang started and played well at right tackle against Dallas but had a mixed performance at left tackle against Minnesota on Nov. 1.
"I definitely feel that T.J. Lang has had an opportunity to play more at the left tackle, so that will definitely help him, with him taking the reps over there today," McCarthy said. "The unfortunate is you still have injuries, and you have to fight through them. But the reality is we've had an opportunity to work a bunch of different combinations, so I think that will definitely help us as we move forward."
No revenge for Martin
On cutdown weekend, the Packers traded veteran offensive tackle Tony Moll to Baltimore for defensive back Derrick Martin. Martin says he marked this game on the schedule after the trade but he harbors no ill will toward his former team.
"No, I've never been a grudge guy," said Martin, though he noted this will be the first time he's ever played against a former team, going all the way back to when he was a little kid. "It's like a neighborhood fight, so I'm going to go out there swinging."
Martin hasn't had a role on defense since the Oct. 5 game against Minnesota, but he's developed into one of the struggling special teams' more reliable players. His 13 coverage tackles trail only Desmond Bishop (17) and Spencer Havner (14). While the Packers rank in the bottom one-third of the league in practically all of the major special-teams categories, Martin said it's only the occasional breakdowns that are preventing the special teams from being a strength.
Hopefully, he's right. With no more patsies on the schedule, the special teams could be the determining factor in any of the final five games — and the factor separating the playoffs from an early vacation.
"I always feel like, once we step on the field as a special teams, it's only one play. It can turn either way," Martin said. "I think our special teams will make sure it turns our way. It's a field position game, you've got to make sure you turn the field position around, and if you can get a turnover out of it, that's even better."
Packers injury report
Out — LB Aaron Kampman (knee). Limited participation — T Chad Clifton (hamstring); RB Ryan Grant (shoulder); CB Charles Woodson (shoulder). Full participation — T Allen Barbre (ankle); LB Brandon Chillar (hand); FB John Kuhn (hand); CB Charles Woodson (shoulder).
The cast on Chillar's hand continues to get smaller, though he joked that nobody should pick him up for their fantasy team, since the chances of him intercepting a pass are pretty slim.
"They are working different types of braces and things inside of the cast just to try to get him more comfortable and more confident with it," McCarthy said. "So as that goes — he wants to play more, there is no doubt about it. He was playing at a very high level before he was injured, but we are definitely working through that."
Rodgers, meanwhile, had little say about his injured ribs, other than they won't prevent him from playing.
Ravens injury report
Did not participate — LB Prescott Burgess (thigh); T Jared Gaither (illness); S K.J. Gerard (thigh); FB Le'Ron McClain (chest); S Ed Reed (ankle and hip); TE L.J. Smith (ankle); LB Terrell Suggs (knee); WR Kelley Washington (illness). Limited participation — LB Ray Lewis (foot). Full participation — QB Joe Flacco (ankle); LB Jarret Johnson (shoulder); DT Haloti Ngata (ankle).
— It's Monday night in December in Green Bay. The early forecast? Low of 23 with a 40 percent chance of snow.
— "Cold weather" and "Lambeau" go together like "Frozen" and "Tundra" The Packers are 18-4 in December-January regular-season home games since 2000. That .818 winning percentage trails only New England (.857), Denver (.842) and Pittsburgh (.826). Probably not coincidentally, all four teams play outdoors in the cold.
— Why is Kampman still not on injured reserve? "There are some procedural things that really I don't know if Ted (Thompson) would even comment on," McCarthy said, "but Aaron Kampman is going to have surgery this week. He will not be back this season."
— Amazingly, this will be the first "Monday Night Football" game played at Lambeau Field in December. The Packers are 10-6 in "MNF" home games.
