Johnson (hamstring) is listed as inactive Thursday against the Lions.
Despite being listed as limited on all three of the Bills' Week 2 injury reports, Johnson will continue to don street clothes on game days due to a hamstring issue that has bothered him since at least Aug. 24. In Johnson's absence, Ray Davis will continue to garner RB reps that don't go to starter James Cook, while Frank Gore is on hand in case one of those two leaves the game for any reason.
