Jennings, who strained a groin late in the season-opening game against San Francisco and was held out of the Chicago game, got through the Seattle contest but aggravated the injury in the first half last weekend against New Orleans.
Rather than have the injury be an ongoing issue, Jennings is prepared to rest the injury until it's 100 percent.
"However long it takes, so I won't have to sit and answer these same questions again," Jennings said on Wednesday. "We don't know what the timetable is. All I know is we're going to take it one day at a time and hopefully it gets better before Sunday, but odds of that happening, they're odd."
Jennings caught a touchdown pass against the Saints but said he aggravated the injury "far before" scoring with 14:15 remaining in the second quarter.
"Gotta be smart now," Jennings said. "To me, honestly, that's where my frustration starts. Be a tough guy – not so much being a tough guy – you just want to go out there and play. There's a difference between being smart with it and being kind of ignorant. First time, OK, we try to be smart, can get through it. Seattle, got through it. Still felt some pain, whatever, made it through the entire game. Sunday, couldn't make it, just couldn't make it. Tweaked it on a play and came back the next series, and tried to continue. And I remember telling a couple of the guys, ‘I'm not going to be able to finish.' I knew I wasn't going to be able to finish, so now it's just a matter of being smart.
"I can't keep having that up and down – I'm in one game, out the next, not sure one game, good the next – I can't keep doing that to myself or the team. That being said, I'm just going to wait until I get 100 percent back healthy and then we'll see 85 back out there."
Packers injury report
Did not participate: WR Greg Jennings (groin); S Sean Richardson (hamstring). Limited: DT Ryan Pickett (shoulder). Full: CB Davon House (shoulder); S M.D. Jennings (neck).
No longer listed on the report is James Starks, who hasn't played this season since suffering turf toe in the second preseason game. "I had a chance to visit with James Starks after practice and really the conversation we had is I really want him to push it," coach Mike McCarthy said. "He's been able to get through a couple weeks of practice. I don't know if he's going to pain-free all year. But this is the week that we want him to try to really, really push through it and see if we can get him involved."
Colts injury report
Did not participate: CB Vontae Davis (ankle); CB Justin King (groin); RB Mewelde Moore (ankle); G Seth Olsen (knee); G Joe Reitz (knee). Limited: LB Pat Angerer (foot); TE Coby Fleener (head); C Samson Satele (knee). Full: LB Dwight Freeney (ankle).
— Mike Neal returned to practice after a four-game suspension. "Had a chance to watch Mike Neal a lot today," McCarthy said. "He looks to be in great shape. He wasn't winded at all. Fresh legs. He had a good practice, I'd like to watch the tape with the coaches and then we'll watch him again tomorrow. I think tomorrow's padded practice will give us a better indication where he is."
We'll have more on Neal later.
— Absent from the injury report is quarterback Aaron Rodgers, who missed a play against the Saints after getting fingered in the eye. He said his eye is fine and he'd "never" wear a visor for added protection.
— McCarthy said special teams was consistently the team's best phase of the game unit during the first quarter of the season. A major focus will be getting the turnover ratio back up to standards. The Packers, perennially at or near the top of the ledger, are minus-1.
— The Colts are coming off their bye week, which will have the Packers on-guard. "They've had an opportunity to evaluate their team after three weeks, so the unscouted look emphasis for us is still heightened going into this game," McCarthy said. "It's something that you see the first couple of weeks of the season and, usually by the fourth or fifth week of the season, you feel like teams are starting to play to certain identities and certain schemes, but this team is coming off a bye week so we're preparing for usual looks and deceptives and things like that."
