Jason Garrison has written a preview of Friday night's game against the Green Bay Packers and the Cardinals. From SB Nation:
Last week, Aaron Rodgers looked impressive in the short period of time that he was in the game, even though the Packers fell to the Browns by a score of 27-17. Rodgers completed six of his eight passes for one touchdown before he was replaced by backups Matt Flynn and Graham Harrell. This week, like Kolb, Rodgers will stay in the game for a longer period of time, and he'll be reunited with his starting tight end, Jermichael Finley, who was placed on injured reserve after tearing his ACL last year in the fifth week of the season.
He's also provided a link to the506 to see if you're lucky enough to be in the area to watch the broadcast live, which will be re-aired by NFL Network over the weekend.
I'm not sure how many possessions Rodgers will play. It probably has more to do with what Mike McCarthy wants to see from the first team offense, and not anything specific with Rodgers. It might have a lot more to do with Finley, who could probably use a few series to get used to running again at full speed in pads.
