The designation was part of the Falcons' moves to reach the 53-man roster limit on Saturday.
The NFL announced the move with Hageman followed charges filed by DeKalb County prosecutors following a March 2016 incident. The league said in a statement its investigation remains pending.
A player on the list may not practice or attend games.
Hageman, a second-round pick in 2014, started four games in 2016.
