Bills head coach Sean McDermott said Johnson (forearm) will not play Thursday against the Dolphins, Ryan O'Halloran of The Buffalo News reports.
Johnson left Sunday's 34-28 win over the Cardinals early and was unable to return. It's not clear how much time the slot cornerback may miss, but the Bills won't take any chances with Johnson on a short week. Cam Lewis took over as slot corner following Johnson's departure Sunday and will likely do so again in Miami.
