The biggest question mark for the Dallas Cowboys on the defensive side of the ball entering training camp is the defensive backfield. While there are some concerns with the interior line and the team’s inability to stop the run, the defensive backfield has even more uncertainty due to injuries. Several players are unavailable to start camp, with All-Pro cornerback Trevon Diggs and Josh Butler, who is returning from a season-ending knee injury, starting on the PUP list. Shavon Revel, the team’s third-round pick in the 2025 NFL draft, will start camp on the non-football injury list (NFI), while 2024 fifth-round pick Caelen Carson will see the field but is returning from a season-ending shoulder injury.
