On May 10, 2014, the Atlanta Falcons signed Nix to a three-year, $1.54 million contract after he went undrafted in the 2014 NFL Draft. He appeared on Hard Knocks with the Falcons. To have a better opportunity to make the 53-man roster, Nix switched positions from linebacker to fullback but was eventually released by the Falcons on August 3, 2014.
