The Facts: The Cardinals are expected to release Peterson today, per source.

Diehards Line: Peterson has a $750,000 bonus due on the third day of league year, Friday, so Arizona saves money. He still could return to Arizona later, a source tells ESPN's Adam Schefter, although that wouldn’t offer Peterson much playing time unless the Cardinals lose David Johnson to another serious injury during the 2018 season. As Profootballtalk.com reminded readers, Peterson had a couple of impressive outings for Arizona, but wound up on injured reserve with a neck injury before the year was out.
