Johnson (hamstring) is listed as questionable for Thursday's game against the Lions.
Johnson sat out the Week 1 victory over the Texans. He returned to a limited practice Tuesday, but he's not quite in the clear yet and his status will probably come down to the wire for the primetime game Thursday. No Buffalo running back has much value outside of insurance behind bell-cow back James Cook, and now Frank Gore has had a chance to enter the mix as yet another option in the Buffalo backfield.
