Johnson sat Week 2 with a calf issue but is on track to start vs Miami after Buffalo’s win at New York and a quick turnaround.

Cam Lewis started at nickel in Week 2, four tackles and a forced fumble; Johnson’s health remains the hinge for Bills’ base-defense plans and run-stopping ability.

Buffalo’s 13-2 mark vs Miami since Johnson was drafted underscores the value of his return, and the short week will test Week 3 roster decisions.
