``Honestly,'' Rodgers said Friday, ``I don't know.''
Rodgers, who dislocated his right (throwing) shoulder when he was tackled from behind while stretching for a first down during a third-quarter scramble against Tampa Bay last Sunday, threw for the first time all week on Friday.
``He has 48 hours,'' Packers coach Mike McCarthy said after practice ended around 12:15 p.m. ``Tomorrow morning, how he feels will be a pretty good indicator. And we'll probably work him out before Sunday's game to see exactly where we're at before we make a decision.
``You hand in the inactives at 10:30 (a.m. Sunday), and I'm sure we'll make our decision close to then.''
After a few prepractice warm-up tosses with strength and conditioning coordinator Rock Gullickson, Rodgers took the first eight snaps of the jog-through session at the beginning of practice, softly throwing the ball on five of them. Rodgers then watched from behind and talked with McCarthy while rookie backup Matt Flynn took the final 15 snaps of the period.
``That was more of a warm-up. And he needed to get the mental preparation,'' McCarthy said. ``There (are) a number of things we felt he needed to see, along with getting Matt Flynn ready.''
While practice continued, Rodgers went inside the Don Hutson Center with athletic trainers Bryan ``Flea'' Engel and Nate Weir for a throwing session. McCarthy stayed at practice and did not watch Rodgers throw. Rodgers then went up to the stadium for treatment and rehabilitation work.
``It wasn't much,'' Rodgers said of the throwing session. ``The strength around (the shoulder) is fine. It's going to be a matter of can I make the throws I need to make? The pain, that's something I can deal with.
``I'm not going to guess. I'm just going to rehab and get ready for Sunday.''
Rodgers, who suffered a season-ending broken foot in 2006 and a torn hamstring that sidelined him late last season, said earlier this week he'd be willing to take a pain-killing injection in the shoulder if necessary.
``It's definitely a different situation not practicing all week,'' Rodgers admitted. ``I feel confident in the game plan, confident in my film study and preparation. It's all about executing the scheme and it's all about how I feel on Sunday.''
If Rodgers doesn't start, he'll be the emergency No. 3 quarterback behind Flynn and fellow rookie Brian Brohm, McCarthy said.
``I think how he feels tomorrow and how he does Sunday before the game will be strong indicators,'' McCarthy said. ``I'm preparing to go either way.''
Asked if he would be more inclined to play it safe and sit Rodgers if he had a veteran backup, McCarthy replied, ``We don't have a veteran backup, so our quarterback structure is exactly what we've talked about. Matt Flynn is the No. 2 and Brian is right behind him, so that's my focus.''
Flynn took the uncertainty in stride.
``I feel like it was a good practice week for me. I feel very comfortable out there,'' Flynn said. ``I just go into it as preparing to play and if Aaron goes, then that's great for this team. But if he doesn't, and I get an opportunity to go, I'm going to do my best for there not to be a dropoff.''
