Johnson took four carries for four yards and caught all three of his targets for 19 yards during Sunday's 36-10 win versus the Ravens.
In a game that Buffalo ran away with in the second half, Johnson's four carries were a season high, but he couldn't produce much on those rush attempts. Ray Davis actually saw more carries (six) in Week 8 and was more effective as a rusher (30 yards). As long as lead back James Cook is available, Johnson won't have much utility in most fantasy formats.
