For the first time in voluntary offseason workouts, Buffalo Bills receiver Stevie Johnson was on the field. He had been forced to watch previous practices because of a lower back injury. "It definitely feels good to just be out there on the field, even through the little pains I have," Johnson said. "It's getting better every week. They gave me a six- to eight-week thing to even get on the field, and it's only been about three, so I feel good." Offensive coordinator Nathaniel Hackett was delighted to see him running routes in individual drills. "It was great to see him," Hackett said. "He looks great in a uni. It was great to see him run some routes instead of being on the side. We've just got to work him back in." Johnson is one of only 13 Bills with at least six years of NFL experience who've reported for workouts -- defensive tackle Alan Branch and linebacker Manny Lawson have yet to -- but with a first-year NFL head coach, a 33-year-old offensive coordinator and a new quarterback, Johnson needs the reps.
