The Cardinals released Johnson on Friday, Adam Schefter of ESPN reports.
Johnson was hopeful that a good situation would emerge in the offseason, but there were no takers, and he eventually landed back with the Cardinals just before training camp. He proceeded to put together a negligible line in the preseason, taking 13 carries for 41 yards. In the end, two fumbles in Saturday's exhibition in Atlanta may have spurred his release, but the performance of younger RB options in Kerwynn Williams and Andre Ellington likely also played a role.
