Johnson (knee) does not have an injury designation for Thursday's game against the Dolphins.
Johnson exited the Bills' Week 1 win over the Cardinals with a knee issue, but the running back was listed as a full participant in Wednesday's walk-through session and will be available to face Miami. He's thus slated to continue to see complementary work along with Ray Davis, behind top back James Cook. In that capacity, Johnson's fantasy upside is limited.
