Early in offseason workouts, Buffalo Bills receiver Stevie Johnson is already dealing with a strained back. â€It’s just frustrating seeing the guys running around, but it’s getting better," Johnson told the team website. Johnson's hoping to be cleared soon so he can get a chance to work with quarterbacks Kevin Kolb, Tarvaris Jackson and E.J. Manuel. Buffalo will express extreme caution given that it's early in the offseason with the workouts technically voluntary. Source: Scout.com
