Buffalo Bills wide receiver Stevie Johnson did not practice Wednesday due to a shoulder ailment that could keep him out of this weekend's game against the rival Miami Dolphins.Johnson suffered the injury late in last week's thumping at the hands of the Dallas Cowboys. Buffalo head coach Chan Gailey remains cautiously optimistic that Johnson will play Sunday."We hope we'll get him out there a little bit Thursday and a little bit
Friday and he'll be ready to go Sunday," Gailey said. "That's what we hope."Johnson, 25, has 44 catches for 531 yards and four touchdowns in nine games so far this season.
