New Orleans Saints veteran quarterback Derek Carr is retiring because of a labral tear in his right shoulder and “significant degenerative changes” to his rotator cuff, the team announced

Now Shough, the Saints' second-round pick (No. 40 overall) and the franchise's highest-drafted quarterback since Archie Manning was taken No. 2 overall in 1971, officially will be competing for the starting position with Spencer Rattler, who's entering his second year, and Jake Haener, who will be in his third.
