Arizona Cardinals wide receiver Michael Crabtree will not play Sunday against the Detroit Lions. Look for rookies Andy Isabella and Keesean Johnson to see more work as a result. Crabtree signed with the Cardinals less than three weeks ago and more than likely needs more time understanding the playbook as well as getting into shape. Look for quarterbackKyler Murray to lean on veteran Larry Fitzgerald and second-year man Christian Kirk early in this game to develop a rhythm.
