Carolina rookie running back Christian McCaffrey is expected to play Sunday in the Panthers-Saints showdown in New Orleans, a source told ESPN's Adam Schefter. McCaffrey is officially questionable on the injury report with a shoulder injury suffered in last weekend's road win against the New York Jets. He was limited in practices on Thursday and Friday. The Panthers and Saints are locked atop the NFC South with 8-3 records, so having McCaffrey will be a significant boost for Carolina.
