The Arizona Cardinals are facing a challenging start to training camp as rookie first-round pick Walter Nolen has been sidelined due to a calf injury sustained at the team's facility. This unfortunate setback raises concerns about the defensive line, where Nolen was expected to make a significant impact. The team will need to adjust their training plans and potentially rely on other players to step up in his absence, emphasizing the importance of depth in their roster.

Head coach Jonathan Gannon will have to monitor the situation closely as the Cardinals prepare for the upcoming season. The injury to Nolen raises questions about the team's defensive strategy moving forward, particularly how they plan to fill the void left by his absence. With training camp just beginning, the Cardinals can only hope for a swift recovery for their promising young talent.
