(WNFL) - Green Bay Packers' quarterback Aaron Rodgers figures that he'll need to practice at least two days before he can return for a game. On his weekly E-S-P-N-Milwaukee radio show, Rodgers was asked if there's any chance he can play on Sunday against the Minnesota Vikings at Lambeau Field. Rodgers said it all comes down to a quote, "risk-reward" comparison. He said the risk would be displacing the left collarbone that he broke November fourth against Chicago. If that happens, Rodgers said he would need a 3-to-5-month recovery. He and the Packers' medical staff would weigh that risk with his ability to go through the motions and be effective -- and he would need at least two days to make that determination. In other words, if we don't see Rodgers practicing on Friday quote, "then I will be spectating" for Sunday's Minnesota contest. The same would be true for the Thanksgiving Day contest at Detroit. He said he would have to be practicing by next Tuesday to have a chance to play at Ford Field on Turkey Day. Meanwhile, most pundits say the Packers must win the Minnesota and Detroit division games to have any chance of making the playoffs. The Pack is a game behind co-leaders Detroit and Chicago.
