Packers quarterback Aaron Rodgers took part in a weekday practice session Thursday for the first time since he tweaked his knee. Rodgers had only been practicing on Saturdays. Head coach Mike McCarthy had said the absence of his team’s best player was having an effect on all the Packers. Tight end Jimmy Graham also returned after missing Wednesday’s workout. The Packers will be taking on a sky-high Buffalo team which is fresh off a stunning 27-6 upset of Minnesota this Sunday at Lambeau Field.
