Carr, 32, was reported "to have suffered an AC sprain," a source with knowledge told NFL Network's Ian Rapoport on Monday (September 25). The veteran quarterback reportedly underwent "a multitude of tests" with none showing additional damage and his timetable for a return "will be determined by the swelling and how he gains mobility," according to Rapoport.
Head coach Dennis Allen later confirmed the AC joint diagnosis and appeared to hint at Carr possibly missing time, but implied that he didn't seem to have suffered a season-ending injury as initially feared.
“I think we're kind of saying week to week. But again he felt better today than he did yesterday. So we're not making any decisions today. We're not ruling anything out. We'll see where he's at as the week goes on," Allen said via Rapoport.
Carr exited in the third quarter of Sunday's 18-17 loss to the Green Bay Packers due to an apparent shoulder injury. The quarterback was taken to a local hospital after undergoing X-rays at Lambeau Field.
Carr finished Sunday's game with 103 yards and one touchdown on 13 of 18 passing. The four-time Pro Bowler signed a four-year, $150 million deal, which includes $100 million in guarantees, with the Saints this past offseason after previously spending his entire career with the Las Vegas Raiders.
