Saints QB Derek Carr left Sunday's game against the Lions with a potential concussion and a shoulder injury.
It sounds like a similar injury to what Carr suffered in Week 10 but was able to avoid missing time thanks to the bye week the following week. That likely won't be the case here. Jameis Winston is in the game and could see more playing time while Carr likely will miss time. Tayson Hill has also been getting more involved as the Saints' Swiss Army knife.
