On the latest episode of “Hard Knocks” Dak Prescott was back in action and Amari Cooper and Trevor Diggs go one-on-one at Dallas Cowboys practice.

On the latest episode of “Hard Knocks” Dak Prescott revealed that he doesn’t like … mascots? Also, one of his backups struggles with interceptions.

Under first-year coordinator Dan Quinn, the Cowboys’ defense is placing a heightened importance on recording interceptions and takeaways.

Second-year wide receiver joins three teammates on reserve/COVID-19 list. Defensive coordinator Dan Quinn also in protocol as team meets virtually.
