I think it may very well come down to this week's game. By their coach's own admission, they need to win out to make the playoffs. If they win next week, they might hold out hope that they can run the table. If not, no reason to expose Rodgers to further damage. I do think some are seeing that Rodgers returned to practice and assume he's close to being ready. Lightly throwing a ball without any threat of contact is a far cry from exposing yourself to getting body slammed by 320 pound defensive linemen. Heck, Rodgers was lightly throwing a ball on the sideline right after he broke his collarbone. Again, broken collarbones can be a very dangerous thing. This is not an issue where he just has to be able to play through pain, he has to be structurally sound. Landing on an already compromised collarbone can be bad, bone could puncture a lung, sever an artery, etc. It's why they shelved Romo after breaking his collarbone even earlier in the season than Rodgers did.
I'm guessing you've seen the last of Rodgers this year.
