The Panthers signed Trask to a contract Sunday, Kassidy Hill of the team's official site reports.
Trask is likely a temporary signing to hold down depth at the position throughout the preseason as current No. 3 quarterback Haynes King (hamstring) recovers from the injury he sustained during Thursday's Hall of Fame Game against the Cardinals. Trask will likely see the field against the Bills next Saturday after Kenny Pickett and the starters get a few drives in. The Panthers waived/injured Malick Meiga (undisclosed) and Nick Hampton (undisclosed) in corresponding moves to make room for Trask on the roster.
