Nolen was placed on the PUP list to begin camp, along with LB BJ Ojulari, and DL Bilal Nichols. This development likely gives Cardinals fans a case of unwanted deja vu. One of Arizona's first-round picks last year, Darius Robinson, played in just six games due to a preseason calf injury.

The pads haven't come on, yet the Arizona Cardinals continue to see big blow after big blow early on this training camp.

The Cardinals' efforts to rebuild their defensive line hit a snag after a calf injury to rookie DL Walter Nolen landed him on the PUP list.

Walter Nolen III’s injury might test the Cardinals early, but a revamped front shows how far this unit has come.
