Colledge, who has never missed a game during his four-plus seasons, is listed as questionable for Sunday's game due to an illness.
"I ate some bad couscous last night and woke up sick this morning," Colledge said. "I'll be fine. Just a one-day thing. I'll be back tomorrow, so no big deal."
Head Coach Mike McCarthy said if Colledge is not able to go on Sunday, rookie Bryan Bulaga would start in his place at left guard.
Fullback Korey Hall also sat out on Friday with a hip injury that he "kind of torqued" during Thursday's practice, according to McCarthy. Hall said he felt it would be beneficial to take the day off on Friday to get ready for the game.
The other Packers in the questionable category for Sunday are linebacker Desmond Bishop (hamstring), who did not participate in practice all week, defensive end Mike Neal (side/rib), who didn't practice on Friday after being a limited participant on Thursday, and cornerback Brandon Underwood (shoulder), who was limited all week.
McCarthy said Neal is "getting close," but was not encouraged by the fact that he wasn't able to practice on Friday after doing some work on Thursday. If Neal is inactive for the second straight week, second-year man Jarius Wynn, who re-signed with the team this week, and rookie C.J. Wilson, could both be up on the 45-man roster.
"We've got some young guys that are getting a lot of reps, and normally those guys get better," defensive coordinator Dom Capers said. "I think that will help us down the road here because some guys have been thrust into positions where they are going to be playing more and they are getting a lot of practice time. I like the energy they bring to practice."
Underwood has been out since sustaining a shoulder injury against the Colts in the Aug. 26 preseason game, and has been wearing a harness to protect the shoulder in practice that he will have to wear in games as well when he returns. Underwood said he felt like his availability for Sunday would be a game-time decision.
Tackle Chad Clifton (knee), defensive end Cullen Jenkins (hand), safety Derrick Martin (ankle), linebacker Clay Matthews (hamstring) and cornerback Charles Woodson (toe) are all probable for Sunday.
Matthews, who posted a career-high three sacks at Philadelphia last Sunday after missing the entire preseason due to the hamstring injury, was limited in practice all week.
"It feels good," Matthews said. "Obviously coming back with 60-plus plays in the game, it was a little sore with the down time that we had.
"I think it is the natural progression with four weeks off and limited practice reps in the first week. Coming out and chasing quarterbacks around all day, it is going to be a little sore. It feels great now. I feel real confident and ready to get after it this weekend."
Familiar facesWhen rookie safety Morgan Burnett makes his Lambeau Field debut on Sunday afternoon, his old college coach will be on the opposite sideline.
Bills first-year head coach Chan Gailey held the same position at Georgia Tech for four years, including his final season of 2007 when Burnett was a true freshman for the Yellow Jackets. Burnett said Gailey paid a recruiting visit to his family's home, which ended up being the night that Burnett committed to play for the Yellow Jackets. Giff Smith, who coaches Buffalo's defensive line, was the recruiting coordinator at Georgia Tech under Gailey.
"It was a good experience (at Georgia Tech)," Burnett said. "With our recruiting class, they made sure they kept us together and built a family-like bond together so that way you felt comfortable being away from home.
"The coaches were great and we had a tight bond. Especially with Coach Smith, we had a tight bond and we still communicate to this day."
Another member of the Bills' staff played a role in the development of one of Green Bay's players. Quarterback Aaron Rodgers was tutored by Bills quarterbacks coach George Cortez for both of his seasons (2003-04) at the University of California when Cortez was the offensive coordinator/quarterbacks coach for the Golden Bears.
"Coach Cortez was big in my development at Cal and we spent a lot of time together studying the offense," Rodgers said. "He did a great job preparing the quarterbacks each week. I think that was really one of his strong points. I'm excited to see him."
Gameday additionThe NFL RedZone channel, produced by NFL Network, will make its debut at Lambeau Field on Sunday afternoon.

Good startAfter leading the league in the category in 2009, one area the Packers were focused on improving in this year was cutting down on penalties.
Green Bay was flagged just twice last Sunday at Philadelphia, which tied Cincinnati for the fewest penalties in the league on opening weekend. The two penalties called on the Packers were the fewest in an opening-day contest for Green Bay since Sept. 7, 1986, vs. Houston at Lambeau Field, when they were also called for two penalties.
Sunday's penalty number also was the fewest under McCarthy since Dec. 30, 2007, vs. Detroit, when the Packers were also flagged twice. The best mark under him came the week before on Dec. 23, 2007, at Chicago, when the Packers were called for just one penalty.
Bills injury/participation updateSafety Cary Harris (hamstring) and linebacker Paul Posluszny (knee) have been ruled out for Sunday's game.
Punter Brian Moorman (back) was added to the injury report on Friday, and is questionable.
Linebackers Antonio Coleman (hamstring) and Reggie Torbor (chest) and center Geoff Hangartner (ankle) are all probable for Sunday.
