Sprained knee
Lions RB Kerryon Johnson is week to week with a sprained knee per source. (Pro Football Talk)
Nerdy Football Analysis: Johnson was on his way to a 100-yard rushing game when he left in the third quarter with what appears to be a sprained knee. It’s unlikely he will play on Thursday leaving LeGarrette Blount, Theo Riddick and Zach Zenner to handle running back duties in Week 12.
