The Falcons signed Colquitt to their 53-man roster from their practice squad Monday, Adam Schefter of ESPN reports.
Colquitt will serve as an emergency punter after the Falcons starting punter, Cameron Nizialek, picked up a hamstring injury during Week 4. Younghoe Koo, Atlanta's placekicker, replaced Nizialek during Sunday's game and had two punts for 70 yards.
