Ridder looks set to start Saturday's exhibition opener against the Saints, and potentially Arizona's following two preseason contests, after coach Jonathan Gannon said Tuesday that Kyler Murray will not play until Week 1, Josh Weinfuss of ESPN.com reports.

Ridder, who was dealt to the Cardinals back in March, appears primed for a busy preseason along with No. 3 quarterback Clayton Tune. After appearing in 19 regular-season games for the Falcons over the last two years, Ridder brings some NFL experience to the table as Murray's top backup, but he won't see much of the field this season if all goes well for Arizona.
