Johnson rushed four times for 34 yards and was not targeted as a passer in Monday's 23-20 win over the Jets.
Johnson was one of two candidates to replace starter James Cook's (toe) touches Monday, but it turned out to be fellow backup Ray Davis (152 combined yards on 23 touches) who benefited from a fantasy standpoint. The 26-year-old Johnson was worth a waiver add Week 6, but given the touch distribution -- plus the potential for Cook to return -- the backup running back is a low-end fantasy option Week 7. The Bills are set to host the Titans on Sunday.
