Detroit Lions running back David Montgomery injured on a running play vs. the Vikings in Week 7, and helped off the field by trainers.

To make matters worse, Lions' running back David Montgomery was helped off the field and appeared to put very little weight on his left leg after being stopped short on a third-and-1 carry. That drive stalled out when offensive guard Kayode Awosika was flagged for a false start on fourth-and-1.
