Brett Favre was back at practice on Wednesday, but he wasn't quite ready to put his bruised elbow, tingling throwing hand and tender shoulder to the test. Meanwhile, it was learned Green Bay Packers' backup quarterback Aaron Rodgers could be unavailable for Sunday's game with the Oakland Raiders and, perhaps, beyond. Favre mostly handed off and threw a few short passes during the portion of Packers' practice that was open to the media. Apparently, he didn't do much more afterward. "It's about where I thought it would be, I guess," Favre said. "Still sore, but I was encouraged today even though I didn't do a great deal." Favre bruised his right elbow and separated his non-throwing left shoulder in the second quarter of the Packers' loss at Dallas last Thursday and didn't return.
