METAIRIE, La. (AP) — New Orleans Saints rookie quarterback Spencer Rattler is scheduled to take his first regular-season NFL snaps on Sunday against the Tampa Bay Buccaneers. Saints coach Dennis Allen selected Rattler as the starter on Wednesday after confirming that usual starter Derek Carr will miss at least one game because of a left oblique injury that occurred in the fourth quarter of New Orleans’ 26-13 loss in Kansas City on Monday night. The decision means that Rattler, for the time being, moves ahead of second-year pro Jake Haener on the depth chart. Haener replaced Carr after his injury in Kansas City and also played late in a pair of lopsided victories to start the season. “We just internally talked a lot about it and felt like in this particular game he was going to give us the best chance to win,” Allen said of Rattler. “He’s a rookie so we’re going to have some challenges that go along with that but I think we’ll have a good plan for him.” Rattler was selected by the Saints in the fifth round of last spring’s NFL draft out of South Carolina.
