David Montgomery, running back for the Detroit Lions, is not practicing due to a thigh injury. Montgomery mentioned that he may need a couple of weeks to recover, while coach Dan Campbell described his status as day-to-day. With Montgomery out, Jahmyr Gibbs is expected to be the top back, with Craig Reynolds and Zonovan Knight providing depth. Gibbs will likely see the majority of playing time, with Reynolds getting some carries and potentially a few targets.
