The Facts: The New Orleans Saints not only suffered a heartbreaking loss to the Detroit Lions, they may be without Carr for an extended period. Carr exited Sunday's game in the second half due to shoulder and back injuries. The Saints also announced that he is in the league's concussion protocol. "Derek is in the concussion protocol right now," head coach Dennis Allen said after the game. "We will evaluate that as we go."

Diehards Line: Carr was injured in the fourth quarter after sustaining a huge hit from Lions pass rusher Bruce Irvin. Irvin was penalized for roughing the passer on the play. Shortly after the play, Carr was carted off the field and did not return. Veteran Jameis Winston replaced Carr at QB for New Orleans. Before his injury, Carr completed 17 of 22 passes for 226 passing yards, one touchdown and an interception. Jamies Winston, who took over in the fourth quarter, managed to rally New Orleans back in the game but the comeback fell short. Winston finished the game 2 of 5 for 41 yards. New Orleans next faces the Carolina Panthers in Week 14.
