Trask signed with the Falcons' practice squad Wednesday, Terrin Waack of the team's official site reports.
The 2021 second-round pick from Florida was cut by Tampa Bay in late August after failing to make the team's initial 53-man roster, but he's since found work in Atlanta. Trask is now expected to operate as the Falcons' emergency third quarterback, playing behind Kirk Cousins and Easton Stick.
