Arizona Cardinals linebacker Dennis Gardeck has been ruled out for the rest of the season after suffering a torn ACL during the second half of the team's recent victory over the Los Angeles Chargers. This marks Gardeck's third ACL injury, and he had been leading the team with three sacks and six tackles for loss prior to the injury. The Cardinals' defense has already experienced multiple setbacks this season, including injuries to other key players such as BJ Ojulari, Justin Jones, and Bilal Nichols. In Gardeck's absence, Julian Okwara is expected to step into a starting role alongside other linebackers. Rookie Darius Robinson, the team's first-round pick, is anticipated to make his debut soon, providing some hope for the defense moving forward. The Cardinals, currently dealing with a series of injuries, will need to adjust their strategy to maintain their defensive strength.
