Bills wide receiver Stevie Johnson was absent from Bills practice on Friday, for unknown reasons according to Joe Buscaglia of WGR55 in Buffalo. Johnson was not listed on the injury report heading up to the week-concluding session. It could be one of two things for the Bills. It's either a rest day to get him ready for the game on Sunday, or something occurred in practice on Thursday that kept him out of working with the team. More will be learned when coach Chan Gailey addresses the media. Source: The Redzone
