The Facts: The Saints confirmed that Carr did suffer a concussion in Sunday's loss to the Lions.

Diehards Line: It's Carr's second concussion in less than a month. HC Dennis Allen said he is also being evaluated for a rib injury (the one that was announced as a back injury during the game). Allen said he believes Carr’s shoulder came out OK though. ... Jameis Winston will get the start this week if Carr can't go.
