Kevin Smith: Quad Strain?

Smith left practice Wednesday with an apparent quad strain, MLive.com reports.

This is exactly what the Lions don't need, another running back going on the shelf with an injury. There's no indication this is a serious injury, but, still, with Jahvid Best (concussion) and Mikel Leshoure (suspension, hamstring) already sidelined, the Lions can ill afford to take another hit on their depth chart. Keiland Williams and Joique Bell are next on the depth chart should the Lions be forced to move further down the food chain.
