The Dallas Cowboys have suffered a significant setback before the start of training camp, losing defensive end Sam Williams for the entire season due to a torn ACL in his left knee. The injury occurred during a special teams drill, and Williams was unable to put weight on his leg as he was carted off for medical evaluation. This loss is particularly impactful as the Cowboys were counting on Williams to bolster their pass rush alongside established players like DeMarcus Lawrence and Micah Parsons.

• Sam Williams' injury is a major blow to the Cowboys' defense, impacting their pass rush strategy.
• The Cowboys are looking to new draft pick Marshawn Kneeland to step up in Williams' absence.
