The Bengals signed free agent defensive end Immanuel Turner. They waived halfback Darrin Hall in a corresponding move.
Turner originally signed with the Cardinals as a college free agent on May 10. Arizona waived him July 20.
He made 58 career tackles and five sacks at Louisiana Tech.
Hall, a rookie out of the University of Pittsburgh, joined the Bengals on May 7 as a waiver acquisition from Cleveland.
The Bengals also announced they placed linebacker Noah Dawkins, long snapper Clark Harris and center Billy Price on the non-football injury list.
