The Dallas Cowboys have signed veteran defensive end Carl Lawson to strengthen their defensive line after losing Sam Williams to a season-ending ACL injury. Lawson, who struggled to find his footing with the New York Jets last season, played only six games in 2023 but had a productive 2022 season with seven sacks. This signing follows the Cowboys' recent trade for defensive tackle Jordan Phillips from the New York Giants. Additionally, the Cowboys added defensive end Al-Quadin Muhammad but waived Shaka Toney due to an injury designation. These moves aim to address the depth issues following several departures and injuries on the defensive front. Despite these additions, the Cowboys are still working on contract extensions for key players like CeeDee Lamb.
