Lions RB Stefan Logan was carted to the locker room in Friday's preseason game with a right ankle injury. Lined up in the backfield for a handoff from Matthew Stafford, Logan lost his footing, falling to the ground while exposing Stafford to a big hit. Logan walked off the field with relatively little assistance, but looked to be in a great deal of pain on the sideline. A serious injury would further decimate a Lions' running back corps that's perilously low on healthy bodies. Logan had zero carries before going down, and just one catch for two yards.
