The Cowboys were just getting their regular tackles back on the field, and they may have lost another one.
Hyatt went down during individual drills, and is expected to get an MRI soon to determine the extent of the injury. He spent most of last year on their practice squad, getting a late promotion but he did not appear in a game.
The Cowboys have been plagued by tackle injuries and illnesses all camp. Thursday was actually the first time left tackle Tyron Smith, right tackle La’el Collins, and swing tackle Cam Erving participated at the same time.
