However, the Bengals elected to move on and released him in a move that cleared $1.4 million in available cap space. The Falcons signed him to a contract a few weeks ago.
In 2015, Hawk appeared in all 16 games for the Bengals and recorded 24 tackles and sack. Pro Football Focus has him rated as the No. 52 linebacker out of 97 qualifying players.
