The Cowboys signed Trask to the practice squad Tuesday.
Trask is best known for his time with the Buccaneers. In seven regular-season appearances with Tampa Bay, the 2021 No. 64 overall pick attempted only 11 passes, completing four of them. Trask is seemingly a long way from being active for an NFL game and may only see the field as an emergency quarterback. That likely won't change as long as Dak Prescott and Sam Howell are available.
