Arizona’s revamped defensive front faces early adversity with a first-round pick and two core pieces sidelined just as training camp begins.

The St. Louis Cardinals' front office will be busy over the next nine days deciding whether to buy, sell or do a bit of both before the July 31 trade deadline.

Johnson, the 47th overall pick in the draft this year, signs his rookie deal on the day he reports foro training camp.

Cardinals cornerback Will Johnson made it official, signing his four-year rookie contract ahead of Wednesday's first practice.

“He’s gonna miss some time” #AZCardinals HC Jonathan Gannon on Walter Nolen’s calf injury. “I don’t know” when asked if Nolen could miss time in the regular season. Said he hurt his calf training. Nolen, BJ Ojulari (knee) and Bilal Nichols (neck) also set to miss time.

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.
