Rattler will start Saturday's preseason game against the Jaguars, per Saints head coach Kellen Moore.
Rattler will get the first opportunity to make his case for the backup role behind Tyler Shough. Zach Wilson is competing for the second spot on the Saints' quarterback depth chart as well, and New Orleans also has Hunter Dekkers in the QB room. Rattler and Wilson are likely to both see plenty of preseason action as the Saints sort out their backup QB situation.
