The Dallas Cowboys are adding more depth to their defense before Sunday’s NFC East game against the Washington Commanders.

NFL insider Adam Schefter reports that the Cowboys have called up linebackers Justin Barron and Curtis Robinson from the practice squad for Sunday’s game against Washington. Dallas is making these moves because injuries have raised concerns about their defense.

Linebacker DeMarvion Overshown will miss Sunday’s game after hurting his hamstring in Dallas’ Week 1 loss to the New York Giants. He is expected to be out for several weeks, so the Cowboys lose one of their key young defenders.

Safety Malik Hooker is also out after breaking his forearm and needing surgery. Without him, the Cowboys have even less depth on defense as they get ready for their second game of the season.

With Overshown out, rookie linebacker Jaishawn Barham is likely to play a bigger role against Washington. The third-round pick might start at linebacker and take over defensive communication for the Cowboys.

Barron and Robinson give Dallas more choices at linebacker. Robinson adds veteran experience, and Barron now has a chance to help after being on the practice squad. These moves could be important if the Cowboys need to rotate linebackers during Sunday’s game.

The Cowboys are hoping to recover from their Week 1 loss to the Giants. Washington is also searching for its first win after losing to the Philadelphia Eagles in their opener.

Dallas will rely on its larger linebacker group to try to stop the Commanders and avoid starting the season 0-2. With several defenders out, the Cowboys’ extra depth could make a big difference in this NFC East game.
