The Falcons signed Rourke to a contract Thursday, Terrin Waack of the team's official site reports.
After being let go by the Giants on Sunday, Rourke wasted no time finding another team as the Falcons released quarterback John Paddock in a corresponding move. Rourke, a one-time star in the CFL, will use training camp as an opportunity to compete against Taylor Heinicke for the emergency quarterback role behind presumptive starter Kirk Cousins and 2024 eighth overall pick Michael Penix.
