According to Tom Silverstein of the Milwaukee Journal-Sentinel, injured Packers QB Aaron Rodgers will be medically evaluated today. From what I've read, this evaluation will likely decide whether or not Rodgers will play this week, so yea, its result is kinda a big deal.
In his tweet, Silverstein also mentioned that #12 "has a pretty good idea" on how the evaluation will go. Now since he's been practicing so well lately, I can only believe that he believes it'll go well. But, as always, I could be wrong. Although, as of now, I can't say I know anybody who thinks I am.
