The Cowboys signed veteran wide receiver Antonio Callaway and rookie center Brock Hoffman to the practice squad. Callaway was a fourth-round pick in 2018 out of Florida that has totaled 695 yards and five touchdowns in his career. In a pair of corresponding moves, Dallas placed undrafted rookie center Alec Lindstrom on the practice squad injured reserve list due to a back injury and released defensive end Mike Tafua.
