Derek Carr, the quarterback for the Saints, left the Lions game with head, back, and shoulder injuries and is now in the concussion protocol.

Quarterback Derek Carr was struck hard in the backfield by Bruce Irvin during the fourth quarter of the New Orleans Saints' 33-28 loss to the Detroit Lions, and he took a while to stand up.

 Eventually, Carr's right arm was being held by trainers as they assisted him off the field. Carr was replaced under center by Jameis Winston. 

Carr underwent a concussion evaluation in addition to having his back and shoulder injuries officially listed as unlikely to return. He never showed back.

Carr eventually got up and left, but not before the cart was pulled out for him. On the aforementioned play, Irvin was penalized for roughing the passer.

Before leaving the game, Carr completed 17 of 22 passes for 226 yards, one touchdown, and one interception. In his place, Winston completed 2 of 5 passes for 41 yards. 

Following the game, reporters were informed by Saints head coach Dennis Allen that Carr was being assessed on "a couple of different things" in addition to being in the concussion protocol.

It looks like he might not be able to play for New Orleans against the Carolina Panthers in Week 14.
